Artisan bread

A bake-day studio for bread: a library of about ninety breads from pain de campagne to injera, bagels and panettone — each with its formula, timed process, techniques, shaping and bake — a sourdough tab (starter types, a bulk-time model with the aliquot target, converting recipes to and from sourdough, rye sours, discard), braid, bagel, pretzel and pita drawings, hearth-style formulas from baguette to 100 % rye, preferments worked out from a straight dough (poolish, biga, pâte fermentée, levain, scalds) with their timing by temperature, a printable bake-day plan with fold timers and an aliquot-jar bulk target, shaping and scoring drawings, steam and oven set-ups, crumb troubleshooting and a flour guide.

How to use it

How to use it

Pick a bread at the top — country loaf, pain de campagne, baguette, ciabatta, fougasse, whole-grain levain, porridge loaf, 40 % and 60 % rye, 100 % rye with a scald, or focaccia. It sets the formula, the preferment, the process and the oven on every tab. The Library tab has about ninety more breads from around the world. They are typical starting points written for this tool, not anyone’s house recipe. This tool is about the process; the bread tool edits formulas in detail, and the sourdough planner looks after the starter.

Styles

The formula for any number and weight of loaves, in grams, as baker’s percentages of the flour rows and as shares of all the flour (counting the flour in a levain or rye sour), with the true hydration and salt. The process cards give the mixing, bulk, folds, proof and bake at a 24 °C dough, and the notes say what is particular to the style. Links open the formula in the bread tool and the levain build in the sourdough planner.

Library

About ninety breads, each with its formula, the process step by step, the techniques that make it, shaping, scoring or finish, the bake and what tends to go wrong. Filter by tradition (French, Italian, German, Nordic, British and Irish, Jewish and Eastern European, Middle Eastern, South Asian, African, East Asian, the Americas, modern sourdough), by leavening (commercial yeast, levain, rye sour, lievito madre, sweet stiff starter, chemical, steam, unleavened), by method (hearth, tin, flatbread, griddle, steamed, fried, boiled then baked), by enrichment, flour, difficulty and total time — or search. Among them: the sourdough family (country, San Francisco, whole wheat, spelt, einkorn, emmer, seeded, baguette, ciabatta, focaccia, sandwich loaf, bagels, English muffins, brioche, pizza, discard crackers); rye breads from Roggenmischbrot and Vollkornbrot to pumpernickel, rugbrød, Borodinsky and ruisleipä; French, Italian (with panettone, pandoro and colomba on lievito madre), German, Nordic and British breads; challah, babka, bialys and bagels; pita, lavash, barbari, sangak, naan, roti, paratha, puri and injera; milk bread, shokupan, mantou and bao; pandesal, pão de queijo, bolillo, tortillas, Cuban bread, cornbread, popovers and Boston brown bread.

Set the number of pieces and their weight for grams. The formula opens in the bread tool like the styles do, a levain build opens in the sourdough planner, and Plan bake day plans the bread back from when it goes in the oven. Process times are for a 24 °C dough; the fermentation steps follow the dough temperature set on the Bake-day plan. The library is loaded only when you open it.

Preferments

Enter a straight dough — all the flour, water, salt and yeast mixed in one go — and choose a preferment:

  • Poolish: equal flour and water, a pinch of yeast, 8–16 hours.

  • Biga: stiff (45–60 % water), slower, stronger.

  • Pâte fermentée: a piece of finished dough, salt and all, fermented ahead.

  • Levain: a sourdough build from your starter, seeded 1 : x : x.

Choose how much of the flour is prefermented, the preferment’s hydration, and when you want it ripe and at what temperature. The tool splits the dough into the preferment and the final dough, keeping the totals the same, works out the preferment’s yeast for that time and temperature, and lists how long it would take at other temperatures. Final-dough yeast is cut in proportion to the flour already fermented — a starting point.

Scalds — tangzhong (cooked to 65 °C), yudane (boiling water, rested overnight) and the rye Brühstück — gelatinise part of the flour’s starch so it holds more water: a softer, moister crumb that keeps. The tool gives the flour and water to use and what is left for the dough.

Sourdough

Starter care and the levain build for a recipe are in the sourdough planner; this tab is about choosing and using a starter.

  • Starters: liquid and stiff levain, rye sour, lievito madre (with the bagnetto and legatura) and a sweet stiff starter — what each is for and how to switch hydration in one feed.

  • Fermentation model: bulk time from the levain percentage, its hydration and the dough temperature, a table of times, and the aliquot-jar rise to aim for.

  • Convert a recipe: a yeasted dough to sourdough (the levain carved out of the same flour and water, the yeast gone, the bulk estimated), or a sourdough formula back to yeast — straight, or with a poolish in the levain’s place.

  • Controlling sourness: hydration, temperature, inoculation, flour, retard and starter care, and which way each pushes.

  • Rye sours: why rye needs acid, and a single-stage or three-stage Detmold sour in grams.

  • Discard: ideas, and how much flour and water to take out of a dough when discard goes in.

Bake-day plan

Set when the loaf goes in the oven and the dough temperature. The plan works backwards through the preferment, autolyse (or fermentolyse, with the leaven in), mixing (Rubaud or slap-and-fold by hand, stand or spiral mixer, each with its development target and the windowpane test), optional bassinage, the folds (stretch-and-fold, coil folds, or lamination then coils), bulk, preshape, bench rest, shaping, proof at room temperature or a cold retard, preheating and the bake. Times come from the style at 24 °C and scale with your dough temperature. Choose A library bread to plan the bread picked in the library instead, from its own steps. Print gives a clean timeline; Add to calendar downloads an .ics file with an alert at each step; reminders can beep while the page is open.

Bulk timer and aliquot jar: press Mixing done and the tool counts down to each fold and the end of bulk. Put a little dough in a straight-sided jar, mark the level, and enter the reading now and then: the tool shows the rise against a target that depends on the dough temperature.

Shaping and scoring

Step drawings for a boule, a bâtard and a baguette, and the poke test. More shapes and techniques draws three-, four- and six-strand braids, round, knotted and kaiser rolls, bagels, the pretzel twist, épi, couronne and fougasse cuts, a tin loaf, how a pita forms its pocket, pleated buns, and the lye bath, boiling and steaming set-ups. Scoring patterns — single ear, two parallel cuts, cross, square, hash, wheat stalk, leaf, spiral and baguette cuts — each with the blade angle, depth and what the cut does.

Steam and oven

Dutch oven, combo cooker, stone or steel with lava rocks or a wet towel, or a sheet with a cover: the preheat, the steam phase (lid on), the dry phase, the internal temperature when it is done and how long to cool, for the chosen style.

Troubleshoot

Tick what you see — dense, gummy, tunnels under the crust, flat, tight crumb, pale crust, no ear, blowouts, sour or bland, or for other breads wrinkled bagels, torn braids, pita without a pocket, tough flatbread, soapy quick bread, a slow rich dough, a rye with a hollow under the crust or wrinkled steamed buns — and the likely causes appear ranked, each with a drawing of the crumb it tends to give and what to change. Drawings of six typical crumbs are below, and what tends to go wrong with the bread picked in the library.

Flours

French T, German Type and Italian grades side by side, rye types, US flours by protein, strength (W), how whole wheat, rye, spelt, einkorn and durum behave, and a starting hydration for a blend.

Limits

  • Formulas and timings are typical starting points. Flour, starter, kitchen and oven all move them: the dough, the aliquot jar and the poke test decide, not the clock.

  • Preferment and bulk timings use the rule of thumb that fermentation doubles in speed for every 10 °C warmer, between about 4 and 30 °C. The bulk-rise targets for the aliquot jar are this tool’s own rule of thumb (about 75 % at 22 °C, less when warmer, less before a retard): calibrate them against your crumb.

  • Flour type equivalents are by ash content and only approximate: protein and strength vary between mills.

  • Reminders only work while the page is open; for a locked phone use the calendar file.

  • The library’s formulas and timings are written for this tool as typical starting points; traditional breads vary from town to town and baker to baker.

  • The sourdough bulk model is the sourdough planner’s rule of thumb (about 4½ h at 24 °C with 20 % levain, 1½ h more per halving, doubling per 10 °C cooler, a stiff levain about 10 % slower). The Detmold split of flour between stages is this tool’s own choice; the stages' temperatures and times are the usual ones.

  • Lye (sodium hydroxide) burns skin and eyes: use the food-grade kind, gloves and eye protection, and never aluminium.
