Measurement

Digital Scale

This is the most essential part of your toolkit, and the choice of scale will make a real difference. Choose one accurate to at least one gram, with a large platform and a readout you can actually see when a mixing bowl is sitting on top of it. That last part is the problem with most scales: the display disappears under anything larger than a ramekin, so one with a moveable readout is a great idea.

Current pickapprox. $55
OXO Good Grips 11-Pound Stainless Steel Scale with Pull-Out Display

Primary digital scale

My current scale, the OXO Good Grips 11-Pound Stainless Steel Scale with Pull-Out Display (~$55), solves this elegantly. The readout bar is on a track and slides out from the base: you pull it forward, and it clears whatever container you have on the platform completely. The stainless steel platform lifts off for cleaning, the tare button is where it should be, and it does not ask you to learn anything. It just works.

Pocket precision scale (0.1 g)

Second scale for salt and malt

You will also want a second, smaller scale accurate to a tenth of a gram for salt, malt, and anything else where a single gram is too coarse a unit. I use my coffee scale for this, and a small pocket scale that reads to 0.1 g costs about $15. At the quantities this book works in, salt measured to the nearest whole gram can swing a formula more than you would think.

Thermometer

Temperature beats the clock, but no single thermometer can tell you everything you need to know. An instant-read probe measures your flour, water, dough, and finished loaf; an infrared thermometer reads the surface of your Dutch oven and the walls of your oven; a separate oven thermometer tells you the actual air temperature; and a cheap appliance thermometer keeps the cold-proof shelf honest. Together, they make sure the temperatures you think you have are the temperatures you actually have.

Current pickapprox. $30
ThermoMaven Professional Instant-Read Thermometer

Instant-read thermometer

It also makes the final call of the whole bake: a probe into the bottom of the finished loaf reading 202–204°F is how I know the bread is done, and it is a far more honest answer than the clock or the knuckle-knock.

Instant Read Thermometer

Much better for reading water and dough temperature than the infrared, my instant read gets a thorough workout on bake day, allowing me to know precisely the temperature of my flour, my water, and the dough at every turn, at the beginning and end of bulk fermentation. Those flour, room, and water readings aren't trivia, either. They're the inputs for choosing your water temperature to land the dough temperature where you actually want it, which is covered in "Desired Dough Temperature (Confessions of a Polar Bear)" in Part III. It also makes the final call of the whole bake: a probe into the bottom of the finished loaf reading 202–204°F is how I know the bread is done, and it is a far more honest answer than the clock or the knuckle-knock. Invest in a good one. Once you have it, you will find endless uses, from medium-rare steak to the proper temperature of frying oil for first cook and final crisp phases. I recommend the waterproof ThermoMaven Professional Instant-Read Thermometer (~$30) for its large, easy to read, auto on and off backlit screen that flips over automatically so you can read it from any angle and the fact that you can wash it without worry. You'll need to do that a lot, so avoid ones that don't have this feature, and this is the best one I've ever used.

Infrared Kitchen Thermometer

I cannot imagine a single day in the kitchen without this tool. I primarily use my ThermoPro Infrared Thermometer (~$20) to check whether my Dutch oven has preheated as much as my lying oven claims, and to check the wall temperature of the oven itself for the same reason. This is a great tool in the kitchen, and you will quickly find other uses around the house for it. I often check the registers in my house to make sure my heated or air conditioned air is coming out at the right temp. Plus, the laser doubles as a great cat toy.

Oven Thermometer

I have said it before. Your oven is a big fat liar. If you do not have one of these, you are flying blind. While the infrared reads the surface of the mass in the oven, it does not measure the air temperature. Trust me, the AcuRite Stainless Steel Oven Thermometer (~$10) is the best of the bunch and an essential tool. Mine lives in the oven, hanging on the front of the bottom shelf, where I can see its big, bold numbers through the oven door window with ease.

Refrigerator Thermometer

Your refrigerator lies too, just more politely. Cold proof temperature materially changes the result, refrigerators vary by several degrees from their dial and from shelf to shelf, and after this many pages of me telling you temperature beats the clock, it would be strange not to measure the one your dough spends the longest time at. Any cheap appliance thermometer works; a few dollars. Put it on the shelf where the banneton actually sits, not the door.

Mixing and Fermentation

Water Spray Bottle

A fine-mist water sprayer earns its place all over bake day. I spray my hands and the counter repeatedly rather than using flour, and a light misting keeps the surface of a resting dough from drying into a skin. Some bakers spray the shaped loaf just before scoring to help the blade glide, but I don't; I like my basket flour lines too much to alter their appearance. If you have not noticed by now, I like pretty tools that feel like quality and that I do not mind seeing on my counter, and plastic sprayers are ugly, can leach chemicals into water, and are light and top-heavy and invariably fall over unless filled to the brim. These beautiful Boston Glass Bottle Sprayers (~$8 each) come with labels, in several colors, and just work well and feel good in my hand.

Bulk Fermentation Container

A transparent, straight-sided container turns bulk fermentation from guesswork into something you can actually measure. The vessel matters, but so do the small tools that mark the starting point, show the rise clearly, and keep a light container anchored while you work the dough.

Cambro Containers

I do everything in either a Cambro RFS6PP190 6-Quart Round Translucent Food Storage Container with Lid (~$10) or the Cambro 24PP190 Half-Size Translucent Food Pan ($25 with lid), a low, rectangular version by the same manufacturer, made for commercial kitchens. The round six-quart has markings for volume like a measuring cup, is translucent, has a tight-fitting lid, and will mix dough up to 2 kg, though they come in every size and shape. A rubber band placed on the outside to mark my starting point in the rise stays where I put it, easily and securely. You can use a bowl and cover with a tea towel, but you will not be able to get a rubber band to stay in place, and a transparent container is pretty much required for proper bulk assessment. A tall and narrow container also accentuates the increase in volume.

Extra Thick Rubber Bands

I have been using color coded rubber bands to mark the start and predicted end of bulk fermentation rise, but the regular ones roll over on themselves, they're hard to get and keep straight across the entire container, and they wear out and break quickly. These Heavy Duty Rubber Bands ($6) come in a pack with several colors and are perfect for marking start and end points, and won't roll or sag.

Self-Adhesive 12" (30cm) Sticky Measuring Tapes

The rubber band method is great, but they can be a little hard to get perfectly straight. If you're doing upwards of a hundred bakes for a test protocol, accuracy and repeatability are paramount. These self-sticking ruler tapes read properly when mounted vertically and provide both imperial and metric measurements. I put one on each side of my Cambro containers to help get the bulk fermentation growth measurement just a little finer.

Double-Sided Suction Cups

Listen, you don't have to tell me I'm crazy, but if you baked as often as I do, you'd look for ways to optimize every step, every day, too. I love my rectangular Cambro containers for coil folds, but they're so light that they lift right off the counter with the dough instead of holding still and letting me stretch it.

These cheap double-sided suction cups ($8 for 10) stick to the bottom of the container and the counter at the same time with a little spritz of water from my pretty glass spray jar so I can stretch with both hands to my heart's delight. Small problem but it makes my process so much easier once solved.

Starter Jar and Mixing Tool

Starter and levain work happens in small, sticky spaces, so the useful tools are the ones that can reach the corners, scrape the glass clean, and then get out of the way. A wide-mouth jar gives you room to work; a spurtle or jar spatula does the mixing and cleanup; and the other scrapers and whisks are alternatives, not requirements.

Mason Jars

My starter lives in a wide-mouth mason jar. Wide mouth matters: you need to get a spatula in there, and a narrow jar turns starter maintenance into an act of frustration. I keep at least two going at any time, partly for safety's sake, and partly because a pure white flour starter and a fresh-milled blend each deserve their own jar when I'm running both. The rubber-band trick applies here too: mark the level after feeding so you can see the rise without guessing. If you want to go further than a jar and give your starter an actual warm home, that is a temperature question, and it lives with the proofing boxes at the end of this section.

Bowl Scraper

I use my hand in the container for all mixing, but when I started, I found a flexible plastic rounded bowl scraper helpful, not only with mixing, but with getting the dough out of the container and onto the counter. They are dirt cheap and worth having on hand. A couple of dollars on Amazon, and many companies in the flour and bread space virtually give them away as branding.

Spurtle

The spurtle is a Scottish kitchen tool with a tapered, angled wooden blade. It looks like a very flat spatula crossed with a wooden spoon, and it is genuinely more useful than either for certain jobs. It scrapes the bottom of a jar cleanly, folds ingredients without trapping air, stirs starter without the tines of a whisk getting gummed up, and cleans out a container with a precision that neither a spoon nor a straight-edged scraper can quite match. It is the tool you reach for when nothing else fits. A good acacia wood set of spurtles, like the ones available in five-piece sets on Amazon for around $12–$15, will cover every size of job from a tiny starter jar to your biggest Cambro. I didn't expect a stick of wood to be my favorite new tool, yet I find myself reaching for it over and over again, and not just for my bread work. First, it's pretty, and I've already told you how I feel about utilitarian implements that are also satisfying to look at and touch. The lovely stained wood and gentle curve make it excellent for mixing my starter and levain, and that's where it earns its keep, but because it's narrow, stiff, and sturdy, it's also genuinely useful for other tasks in confined spaces like jars and cups.

Spatula

Mixing your starter in the glass jar gets the sides messy, and I like to see what is going on in there. Even if I have used the sturdier spurtle to mix, my Good Grips Jar Spatula (~$8) does a great job of no-stick mixing and excels at cleaning the sides of the jar so you can see the starter clearly to assess the rise. It is also great for getting the last bits of jam out of a narrow jar for toast, which I consider a perfectly valid secondary use.

Flour Dusting

Dusting flour is a control problem: enough to prevent sticking, not so much that you bury the dough. A shaker or wand gives you a thin, even coat, and rice flour stays powdery where wheat flour can turn to paste against wet dough.

Rice flour

The non-stick powder

Rice flour is the king of non-stick powders for baskets, towels, and transfer mats, and the reason is simple chemistry: rice flour has no gluten, so it never turns to paste against a wet dough the way wheat flour does.

Flour Dispenser (Shaker or Wand)

I have two flour shakers: one for wheat flour and one for rice flour. They come with different hole sizes in the top which control how fast the flour comes out; I use larger holes for wheat and finer holes for rice when dusting my baskets. The Chef Craft Select Dredger/Shaker, Fine, Stainless Steel flour shaker comes in varying screen sizes and comes with plastic covers ($12 for a pair).

There are also purpose-made flour wands, like the OXO Good Grips Baker's Dusting Wand ($15 for a pair), which has a perforated bowl at the end that rotates open for filling and then closes for dusting. It is not necessary, since you can use your hands or any fine-mesh sieve, and it doesn't hold a lot of flour, but it is a nice tool to have if you bake a lot because it gives far better control of a very fine dusting. Why the rice flour gets its own shaker is explained in its own entry below.

Rice Flour

This is not a tool, but it runs through so much of my process that leaving it off the list would be a lie of omission. Rice flour is the king of non-stick powders for baskets, towels, and transfer mats, and the reason is simple chemistry: rice flour has no gluten, so it never turns to paste against a wet dough the way wheat flour does. Wheat flour dusted on a banneton turns to paste against a wet dough and glues the loaf right where you did not want it glued, while rice flour stays powdery and keeps dough from sticking, which is exactly the job. Keep it in its own shaker or one of the new wand applicators, keep it clearly marked so you do not reach for it in a formula, and keep more of it than you think you need. Wheat flour is a poor substitute for any of this, and the first time a proofed loaf releases cleanly from the basket instead of tearing, you will understand why I gave it its own entry. I like to make my own from the lovely scented and aptly named Jasmine rice, but you can also purchase it online if you don't have a mill that can make a fine enough powder. It can also be used to highlight scoring patterns because it stays white while the crust browns around it. I don't love eating unhydrated rice flour so I limit its use, but as an antistick agent, it is king among flours.

Proofing Box

Temperature matters more than the clock, and a proofing box lets you control it instead of merely recording it. A dedicated heated box is the elegant answer, but a seedling mat, carboy heater, warm oven, or cooler can solve the same problem for much less.

Starter Home and Proofing Box (Optional)

Temperature is one variable you cannot fully control, but it is an essential element to track so you can understand how changes will affect your fermentation. The temperature of your dry flour, water, starter or levain, and, of course, the ambient temperature in your kitchen, all affect the process and resulting outcome, and since I have spent so much time telling you that temperature matters more than the clock, I owe you some ideas as to how you can influence or control it. Starter homes, proofing boxes, and other temperature-control tools have been proliferating lately, and a dedicated heated box is a simple tool that lets you actually hold a steady temperature instead of just tracking it.

The Brød & Taylor Folding Proofer (~$255) folds flat for storage and holds a set temperature within a degree or two, which is more than enough, and if that is more than you want to spend, your oven with nothing but the interior light on gets you a warm, draft-free box for free, and a cooler with a jar of hot water in the corner does nearly as well, at least for a while.

There are cheaper ways still. Any thermostat controlled seedling heat mat meant for starting tomato or other tender seedlings will work, costs as little as twenty dollars, and is the cheapest fix for a cold starter I know of. Set your starter jar on one and it can add ten or fifteen degrees, enough to wake a sluggish winter culture that would otherwise take all day to peak. I am not going to pretend this is elegant. It is a seed-starting mat from the garden center sitting in a cardboard box, but a cold starter is a slow starter, and slow is the enemy of a predictable bake schedule, so it earns its place in the drawer. I have also pressed into service the type of heating pad I pull out when my back is in its yearly spasm, a clear plastic soil warming mat, and the Kombucha Carboy Heater ($43) I use now, because it's what I have on hand and it works just as well.

I will be honest that this matters more in my kitchen than it might in yours, because I am a polar bear who keeps my house cold, but if your kitchen runs warm, you may never need one, and if you live in a tropical clime, you may instead need a way to cool your dough to keep it in a reasonable production window. When I started, you had to be creative to find ways to do this. The sourdough marketplace now has all manner of tools for this purpose.

Danish Dough Whisk

A Danish whisk looks like someone bent a coat hanger and attached it to one end of a stick, and it is at best a moderately useful monotasking tool. The open wire loops slide through dry, nascent dough without trapping it all in the middle the way a regular whisk does, but its shape can't mix the dough fully, so you need to switch to your hands almost immediately anyway, eliminating the tool's usefulness. It also traps dough and starter in the nooks and crannies formed by the wire overlaps, so it's just one more thing to have to struggle to clean. Though I initially liked it, the more I used it, the less helpful it felt, and I recently switched to my stout spurtle for the initial mix before switching to my wet (or gloved) hand for the final stage of the initial mix.

Still, they're cool and homey looking, and a good one costs almost nothing; the Breadtopia Danish Dough Whisk (~$12) is the one I'd point you toward. Made in Poland with a beechwood handle and stiff stainless wire, you may find it worthwhile to try.

Bench Scraper

Hands get warm and sticky. Bench scrapers do not. I prefer one with a thin blade profile and a big handle with the sharp corners rounded off, but your hand size will dictate what you find comfortable to use. Make sure it is clean and bone dry before using and between uses, like preshape and final shape, to avoid sticking.

I like the Norpro Stainless Steel (~$12) for its shape and size, thin profile, and measurements printed right on the blade. I really love my Forge to Table Bench Knife (~$85) with leather saya. Unlike a bench scraper, this thing is forged by knife makers and is wicked sharp, hence the saya. It is called a bench knife because you can use it not only to cut and portion dough, but also to chop chocolate, nuts, or other inclusions. The wooden handle and steel rivets are just so damned pretty.

Banneton — Proofing Baskets

A banneton (French derivation), brotform (German for breadform) or proofing basket, is where your shaped loaf spends its final proof before baking. It holds the shape of the dough while it ferments, wicks moisture from the surface to encourage a better crust, and if you do not use a liner, it imprints those beautiful concentric rings onto the exterior of the loaf. This last thing is entirely decorative and I am entirely in favor of it.

You want a round nine-inch for boules and an oval ten-inch for bâtards; those are the two shapes you will bake in this book. Natural rattan is the material of choice. Avoid plastic and silicone. Line them with linen if your dough tends to stick; leave them unlined and well-floured with rice flour if you want the spiral pattern. The rice flour entry above explains why it's my only flour for this job.

A good pair of bannetons runs $25–$40 for a set of two on Amazon; the Saint Germain Bakery Premium Banneton is a solid option. Buy with liners. You can always choose not to use them.

Scoring and Loading

Bread Lame

A lame is a razor blade set into a handle, and its job is to control where the loaf opens as it expands in the oven. Straight, curved, and disc-style holders each change the angle and feel of the cut; the right one is the one you can use precisely and safely.

Lame and Scoring Tools

This thing is called a lame, and it is pronounced lahm, 'cause it's French so you ignore most of the letters. It is a razor blade set into a handle, and its entire purpose is to slash the top of the loaf just before it goes into the oven. That slash, the score, is what controls where the bread opens as it expands in the oven, and it is what gives you the vaunted ear. Without it, the bread finds its own way out, which is usually the wrong way.

I used to prefer a straight handle because it gives you more precision for decorative scoring patterns. My Black Walnut Bread Lame by Zatoba (~$28) is beautiful, fits perfectly in my hand, and makes me happy every time I reach for it, which is a legitimate criterion for a tool you use at a high-stakes moment. Replacement blades cost almost nothing. There are many versions of this style available, and newer versions have magnetic blade covers. I also like the newer disc style blade holder like the Artisan UFO Bread Lame Cutter (~$9 for a set including blades and a case), which holds the blade between two thin discs like a deadly Oreo cookie, and gives you a more natural grip on the blade without fear of bloodletting. My favorites are also made of wood with beautiful carvings on them and are therefore included in my list of pretty things.

That said, I recently discovered the advantage of a curved blade, and this is what most professional bakers I see on YouTube use: a double-edged blade mounted simply on a coffee stirrer stick. It lives in their mouth while shoveling breads into the oven (which terrifies me every time), but I have recently tried a curved blade and the ear it raises is truly epic. A wire lame, a blade mounted on a curved stick, gives you a shallow, angled cut perfect for the classic ear, but I prefer this Baker of Seville Bread Lame ($22 with 6 blades) which can convert from a curved blade to a straight blade by reversing a nut spacer.

A word on the blades themselves: keep the cover on when the lame isn't in your hand, change blades at the first sign of drag rather than pressing harder with a dull one, and when you discard a blade, fold it into a scrap of cardboard and tape it shut before it goes in the trash. Razor blades and trash bags have a long, unhappy history together.

Loading Mat

Loading shaped dough into a screaming-hot Dutch oven should be controlled, repeatable, and safe. A stiff flexible mat lets the loaf slide into place; a silicone sling lowers it with handles and can help with wetter or more difficult doughs.

I use these mats to gently slide the dough into the Dutch oven and it works every time. I believe it to be, by far, the best method for depositing dough in a Dutch oven safely.

Flexible Cutting Mat

These Flexible Cutting Mats (~$10–$15 for a set) are essential to my process. I have tried inverting the dough directly into the Dutch oven and many other methods that I consider dangerous or risky: the dough can get caught on the sides on the way in, stick, and end up misshapen and burned where it touched. I use these mats to gently slide the dough into the Dutch oven and it works every time. I believe it to be, by far, the best method for depositing dough in a Dutch oven safely. A Silpat is too floppy and sticky; it will not work.

Silicone Bread Sling

If you are baking in a Dutch oven or other covered baker, a Koolstuffs Silicone Bread Sling (~$15–$25 for a pair) may be a useful alternative to the flexible mat. It is a long, narrow belt of Silpat-type silicone with a large round or oval section in the middle to support the bread. It lets you lower the dough in and lift the bread back out with handles that are easier to grasp with oven mitts. I use my special sliding mat more than the sling, but both have their advocates and it depends on your Dutch oven geometry. I do find tucking the ends in to the Dutch oven so that the top can fit snugly and hold in the steam to be a little awkward, to be honest, and Silpat is slightly insulating and may affect the bake, but I do use it for some of the more difficult, wet and sticky or slack doughs. Get the pair with one oval and one round if you bake that way.

Decorative Scoring Setup

Decorative scoring gets easier when the loaf can turn beneath a steady hand and excess flour is not hiding the surface. A small turntable and a soft pastry brush are simple tools, but together they make precise patterns much easier to see and execute.

Lazy Susan Turntable

This Acacia Wood Lazy Susan (~$18) is a handsome and practical way to turn your dough instead of your lame when scoring anything fancier than a simple single slash and makes it easier to get your work neat and symmetrical.

Pastry Brush

I sometimes use a pastry brush to remove excess flour from the outside of my loaf or from the mat I use to transfer it, before baking when I remember, and after baking when I do not. A good boar's-hair brush is best, as other types of bristles are too heavy for the job. Pastry Brushes with Boar Bristles and Wood Handles (~$12 for a pair) work well and will not break the bank, but I also have some very nice silicone basting brushes that also work and will not shed hairs onto your dough.

Dutch Ovens and Covered Bakers

My primary vessel is the Le Creuset 5.5 Quart Round Dutch Oven in the classic cherry color (~$420, though it goes on sale). I will not pretend this is an economical choice. It is not. What it is, is a tool I have owned for fifteen years, that distributes heat perfectly, whose enamel interior releases bread without drama, and that I intend to own for another fifty. The price per bake across a lifetime of use is trivial. That said, a Lodge 5 Quart Cast Iron Dutch Oven (~$55) will do exactly the same job for one-eighth as much, though many people find it useful to add parchment paper or a silicone sling under the bread to prevent scorching on the bare cast iron bottom. And if you want one specifically designed for bread baking, with the low section on the bottom and the big pot on the top so there are no deep sides to avoid burning yourself on, you can get the much safer Lodge 5 Quart Cast Iron Combo Cooker (~$55), whose shallow half moonlights as a perfectly good cast iron skillet. If you are just starting out, start there. Upgrade when you are ready.

Dutch Oven Accessory

The pot may already be in your kitchen, but bread temperatures expose its weak points. A heat-safe lid knob makes the lid safe to handle at bread temperatures, and high-temperature parchment can protect the bottom of the loaf when bare cast iron browns too aggressively.

Replacement Lid Knob

If you own a Le Creuset, or end up with one, spend the extra $29 on the Le Creuset Signature Stainless Steel Knob before your first high-heat bake. The stock phenolic knob is the one part of the pot that can't take bread temperatures, and swapping it is a one-minute job with an ordinary screwdriver. The stainless version is rated to any oven temperature, and because I've told you how I feel about pretty things, I'll mention they also come in gold and copper finishes if your pot deserves jewelry. Before I made the swap, I wrapped my old phenolic knob in thick aluminum foil and it survived just fine, so that's your zero-dollar option, but the stainless knob is the right answer.

Parchment Paper

If you bake in bare cast iron, a sheet of parchment under the loaf is the standard insurance against a scorched bottom. Buy parchment rated to at least 450°F; much of the generic supermarket roll tops out at 425 and will darken and turn brittle at bread temperatures. You can also buy preshaped parchment rounds and liners sized for Dutch ovens, some with long paper handles that double as a sling for lowering the dough in. These Blissboard Disposable Parchment Bread Slings are inexpensive and may suit your purpose. One warning from recent experience: a heavy loaf tore the paper handles of one of these slings on the way into the pot. Doubling two slings solved it completely. If your dough runs wet or your loaf runs large, double up. My flexible mats do the loading in my kitchen and my enameled pot does not scorch, so parchment rarely appears in my bakes, but it is cheap, it works, and if your pot is browning bottoms too hard, it is the first thing to try.

Baking Stone

Baking Steel and Stone

Everything in this book bakes in a covered vessel, but a stone or steel still earns its place: parked permanently in the oven, it turns a home oven's thin racks into real thermal mass and steadies the temperature swings my lying oven is prone to. A baking steel is more conductive than a stone and gives you a more aggressive bottom crust; a stone is more forgiving. I run two. My Pizzacraft PC9899 Rectangular ThermaBond Baking and Pizza Stone (~$45) has been in continuous service for years on the bottom shelf, where the Dutch oven sits on it, and the ROCKSHEAT Rectangular Extra Large (23.6" x 15.8", ~$50), nearly the size of a full oven floor, lives on the top shelf, blunting the heat of the top element. Whatever you use, preheat it for a full hour. The thermal mass is the point, so you cannot rush it. If you ever move to open-face baking, loaf straight on the stone with no cover, you will also need a peel to load it and a way to steam the oven, but that is a different book's worth of technique and not how the loaves in this one are baked.

High-Heat Oven Gloves

I preheat my oven at its maximum speed convection, all elements on setting, to 550°F for a full hour. While you may think this is excessive, I am heating up the full thermal mass of not only the oven but the extra stones and steel and the cast iron and enamel of two Dutch ovens, and that's how long it takes to do properly. Everything in there is hot, your dish towel is not up to the job, and your regular oven mitts may not be either. I know this because for two years I used a perfectly nice pair of silicone mitts, but unbeknownst to me, the webbing between the thumb and forefinger wore thin while the rest of the mitt still looked fine. I found out how thin a few days ago, and I have a nicely blistered, oh so painful second-degree burn to prove it.

This is not the place to economize, and it's also not the place to trust a mitt that's been through a hundred bakes. Inspect your gloves before each bake, and retire them at the first sign of wear.

I've recently switched from the clumsier mitt style to the Grill Armor Oven Gloves with fingers, rated to 932°F, EN407 certified, and cut resistant for good measure. The fingers are the real upgrade: gripping a lid handle and steadying a hot combo cooker with actual fingers instead of mitten paws is a real upgraded experience.

Oversized Spatula

This chapter has spent time telling you how to safely get dough into a screaming-hot pot, but you also have to get the bread back out.

You can use any spatula you already own as long as it is stiff enough not to bend under the weight of the bread, and wide enough to support it without the loaf tipping off the edge. A floppy or narrow one turns this into a juggling act at over 500 degrees, which is not an act anyone needs to see.

Cooling Rack

The bake is not over when the loaf leaves the oven. A finished loaf set flat on the counter traps steam under its own bottom crust, condensation has nowhere to go, and the resulting moisture softens the very thing you spent an hour of preheat trying to create, so cool on a wire rack, where air circulates freely. My sheet pans came with racks that fit right inside them, but if yours didn't, they're cheap enough and well worth the investment so your crust bottoms don't go soggy. OXO makes thoughtful, high-quality products, so their Good Grips Non-Stick Pro Ceramic Coated Cooling and Baking Rack (~$23) is an optional upgrade. Whether you get half sheet or full sheet sizes, I make sure mine will sit inside a full sheet pan to catch any stray flour or crumbs. They may be the cheapest things in this entire chapter, and skipping them undoes some of the most expensive.

Bread Knife

You do not need a dedicated bread knife. You need something serrated, but it doesn't have to be a dedicated bread knife, and honestly, even the dedicated ones aren't my only solution. A regular serrated blade is flat and, with my prized crust, it is hard to get it through the center-bottom of a large boule without a lot of sawing. Bread knives should have aggressive serrations, a curved belly, and an offset handle to let you apply pressure to the bottom crust without your knuckles hitting the cutting board. Relatively inexpensive, but even a good bread knife is not the best way to get perfect slices every time.

Manual Bread Slicer

You do not need, but I promise you will love, the CAWIU Upgraded Manual Spiral Bread Slicer (~$50), a deli-slicer-looking knockoff of the $300+ Zassenhaus Classic that may be even better than the original. I have a very nice collection of knives including several bread knives, which do a pretty good job but are still difficult and dangerous to use on a hard-crusted boule. This thing is solidly built, attractive with its enamel finish, makes perfect slices, is easy to use, and small enough to store easily in its included hard-shell cover. I cannot possibly oversell how much better this is than I expected it to be. You do need to be careful to avoid cutting off your thumb as you push the bread toward the blade, so I bought some Microplane cut-resistant gloves for my wife lest she de-digitize herself. It is amazing how much cleaner a job it does than even my expensive French bread knife.

Bow Knife

A bow knife is a dedicated bread knife made of a bow-shaped wooden handle with a serrated blade ribbon strung under tension at the ends of the bow, leaving a narrow space between the bow and the blade in which you cut your slices of bread. I understand why these things exist, and they are very pretty to look at, but I need to issue a warning. The problems with this product are not readily apparent until you try it, so I thought I'd save you some time and money. First, it's impossible to use one to cut a bread in the middle or anywhere other than less than an inch from the edge of the bread, and worse, the wider the bread, the closer it comes to the bow ends and therefore the shorter the cutting strokes you can make. The use of this thing is so limited in capability that it becomes nearly useless and will likely end up in the bottom of a drawer, or even worse, the garbage. It's pretty to look at, but a terrible design. Skip it.

Grain Mills

If you have read the milling chapter, you already know that I think milling your own flour is one of the most powerful ways to take control of your bread. Here I am not going to revisit the philosophy. This section is simply about equipment.

The mill I use is the Mockmill Lino 200 (~$700). It is a beautiful machine, which matters to me more than it probably should, but it is also a genuinely excellent stone mill. It lives on my counter, mills flour quickly, produces a very consistent grind, and has been completely reliable. If I were replacing my mill tomorrow, I would buy another one without hesitation.

The Mockmill is a stone mill, meaning the grain is crushed and sheared between millstones rather than shattered by steel teeth. Stone mills tend to produce flour with a texture many bakers prefer, particularly for artisan bread. They are generally quieter than impact mills, though still far from silent, and they allow a wide range of grind adjustments from coarse meal to fine flour.

The other major category is the impact mill. The most common examples are the WonderMill and NutriMill. These mills use high-speed steel heads to pulverize grain into flour. They are typically faster, often collect flour more cleanly, and can be easier to live with when milling large quantities. They are also considerably louder. The flour they produce is excellent, and many serious bakers use them happily. If your primary goal is efficiency rather than romance, an impact mill deserves consideration.

For bakers interested in complete self-sufficiency, hand-crank mills remain available from manufacturers such as Country Living and Diamant. They work well, but I view them as specialty tools, emergency tools, or historical curiosities rather than practical everyday bread-making equipment. Milling enough flour for a pair of large sourdough loaves by hand is an excellent way to discover muscles you did not know you had.

If you are serious about fresh milling and can afford it, buy a quality electric mill. You will use it more often, enjoy it more, and make more bread.

Bolting Screens

If you want control over extraction levels, you will eventually want bolting screens. I recommend buying both a #40 mesh screen and a #60 mesh screen in the largest diameter you are happy to store. The larger size will make a frustratingly slow process a little faster and easier. Those two sizes will cover almost everything a home baker is likely to do.

The #40 screen removes the largest bran particles while allowing most of the flour and finer particles to pass through. It is excellent for creating a high-extraction flour that still behaves much like whole grain flour but with improved handling characteristics.

The #60 screen is considerably finer. It removes additional bran and larger germ particles, producing a flour that behaves much closer to a traditional artisan bread flour while still retaining far more of the grain than commercial white flour. It is my preferred screen when I want to experiment with different extraction levels or create multiple fractions from a single milling session.

One of the pleasures of owning both screens is that they allow you to separate a milling into several useful streams. The finest flour can go into bread. The larger bran fractions can be used for muffins, crackers, bran soakers, coatings on proofing baskets, or even decorative crust treatments. Nothing needs to be wasted.

You do not need bolting screens to make excellent bread. Plenty of wonderful loaves have been baked from 100% extraction flour straight from the mill. But if you enjoy experimentation and want precise control over flour behavior, a #40 and a #60 screen are among the most useful accessories you can own.

Automatic Sieve Shaker

A real indulgence, but a tool that makes my life easier and my kitchen messier, this automated shaker took the single most tedious job in my milling routine and turned it into something I can walk away from. Bolting by hand is slow. You shake, you tap, you swirl, you switch hands, you check your progress, and twenty minutes later you have a bowl of high-extraction flour and a sore wrist. The Sidasu Automatic Vibrating Sieve Shaker (~$168 with both the 40 and 60 mesh screens) does the same job with a vibrating motor while I clean the mill, feed the starter, or just stand there feeling smug. Pour the fresh-milled flour in the top, put the lid on, flip the switch, and the machine buzzes the flour through the screen and into the collection pan below while the bran stays behind.

Two honest warnings. First, it takes one screen at a time, so a two-stage bolt still means two passes, though each pass runs itself. Second, it earns the "messier" in my opening sentence: a vibrating drum full of the finest flour particles will find every gap you did not know it had, and a fine dust settles on everything nearby until you learn its habits. Run it inside a sheet pan, or better, near the sink and away from anything you love.

Nobody needs this machine. Hand screens do the identical job for a tenth of the price, and if you bolt flour once a month, they are the right answer. But if fresh-milled, high-extraction flour is a weekly habit rather than an occasional experiment, this is the difference between bolting being a chore you dread and a background hum you ignore. Mine has moved from indulgence to fixture.

Stand and Spiral Mixers

I do not think you need a stand mixer to make exceptional bread, and I want to say that clearly before I tell you that I own one and use it. The point of this book is that you understand what is happening in the dough, and a mixer can distance you from that understanding when you are learning. Your hands give you information a mixer cannot.

That said, once you know what well-developed dough feels, looks, and behaves like, a mixer is a legitimate time-saver for certain styles of dough, particularly high-hydration loaves that require extended mixing, and for bakers who have physical limitations that make extended hand mixing difficult.

If you go that route: the KitchenAid Artisan 5 Quart (~$350–$450) is the household standard and does a perfectly good job with the dough hook, though it is a planetary mixer rather than a machine designed for dough, and overworking the gluten is easier than you would think. A dedicated dough mixer is the step up. The Ankarsrum, with its open bowl and roller, is a purpose-built bread machine in a class of its own, and true spiral mixers such as those from Famag bring the geometry professional bakeries use, but figure $800 as the starting point and climb from there. The newest entries come from Ooni, of pizza oven fame: the Halo Pro Spiral Mixer ($799) puts a true rotating-bowl spiral mixer on a home counter with a big 7.3-quart bowl, and the brand-new Halo Core ($599) packs the same spiral action into a machine a quarter smaller for more modest batches. Whatever the machine, the variable to respect is dough temperature: a mixer's friction warms the dough as it works, so the machine changes your water temperature math, not just your effort. I would not start there. Get your hands in the dough first.

The book teaches what to look for; the site tells you what to buy this week.
