Bread is flour, water, salt, and yeast — or a wild culture of yeast and bacteria in the case of levain. Everything else is technique. A standard white bread begins at 65% hydration (650g water per 1000g flour), 2% salt (20g), and 1% instant yeast (10g), expressed in baker's percentages where flour is always 100%. These ratios produce a dough that is workable, well-seasoned, and ferments reliably at room temperature (21-24°C/70-75°F) in approximately 1.5-2 hours for bulk fermentation. Flour is the skeleton. Bread flour (strong flour in British terminology) carries 11.5-13% protein, providing the gluten necessary to trap fermentation gases and create structure. The protein content directly dictates crumb: lower protein yields a tighter, cakier texture; higher protein yields the open, irregular holes of a well-made ciabatta or country loaf. Within bread flours, the origin matters — North American hard red winter wheat produces a tenacious, elastic gluten, while French T65 or T80 flours yield a more extensible, less springy dough that ferments differently and produces a more delicate crumb. The quality hierarchy: (1) Competent — the bread is fully baked (internal temperature 96°C/205°F), the crust is golden, the crumb is even without dense, gummy patches. (2) Skilled — the crust is deeply caramelised and shatters audibly when pressed, the crumb shows an irregular open structure with a range of hole sizes, the flavour has developed complexity from fermentation with faint lactic and acetic notes. (3) Transcendent — the crust sings when it comes out of the oven (the crackle of contracting, perfectly caramelised starches), the crumb is translucent at the cell walls with a gossamer quality, the aroma fills the room with a depth that speaks of long fermentation, and the flavour evolves as you chew — sweet wheat, then tang, then a lingering nuttiness. Autolyse is the first critical technique: mixing flour and water and resting for 20-60 minutes before adding salt and yeast. During autolyse, flour hydrates fully and enzymes (amylase and protease) begin breaking down starches and proteins, producing a more extensible dough that requires less mechanical kneading and develops superior flavour. Salt is added after autolyse because it tightens gluten and slows enzyme activity — adding it too early defeats the purpose. Bulk fermentation is where the bread develops 80% of its flavour. During this phase, yeast converts sugars to CO2 and ethanol while lactobacillus bacteria (present even in commercial yeast doughs, though in smaller numbers than sourdough) produce organic acids that create complexity. Stretch-and-fold every 30 minutes during bulk — 4 sets of folds — builds strength without degassing. The dough should increase in volume by 50-75% (not double — over-fermentation weakens the gluten and produces a flat, dense loaf). Where the dish lives or dies: shaping. A properly shaped loaf has surface tension — the outer skin pulled taut around the mass of dough, creating a smooth, drum-tight surface that directs the oven spring upward rather than outward. Without tension, the loaf spreads flat. With too much tension, the surface tears during baking. This is the baker's most tactile skill, and there is no shortcut to developing it. Bake in a preheated Dutch oven at 245°C/475°F with the lid on for 20 minutes (trapping steam for crust development), then lid off for 20-25 minutes for colour. The Japanese milk bread (shokupan) and Indian naan share bread's foundational four — flour, water, salt, leavening — yet diverge in enrichment and method, proving that mastery of the base unlocks every variation.
Baker's percentages are the universal language. Every ingredient is expressed as a percentage of total flour weight, making recipes infinitely scalable and comparable. A 70% hydration dough is a 70% hydration dough whether you are making one loaf or one hundred. Hydration governs crumb openness: 60-65% produces a tight, sandwich-style crumb; 70-75% produces an open, rustic crumb; 80%+ enters ciabatta and focaccia territory, requiring advanced handling skills because the dough is slack and sticky. Water quality matters — chlorinated municipal water can inhibit yeast activity; if your tap water smells of chlorine, let it stand uncovered for an hour or use filtered water. Yeast quantity is inversely related to time: more yeast means faster fermentation but less flavour development. Professional bakers use minimal yeast and long, cold fermentation (retarding at 3-4°C/38-40°F for 12-72 hours) to maximise flavour while fitting baking into a production schedule. Salt is 2% by tradition and science — below 1.5%, bread tastes flat and ferments too quickly; above 2.5%, yeast activity is significantly inhibited and the crumb tightens. Oven temperature must be high — bread needs intense initial heat to drive oven spring (the rapid expansion of gas in the first 10 minutes of baking) and to trigger the Maillard reaction and caramelisation that create crust flavour. Steam in the first phase of baking keeps the crust flexible long enough for maximum spring before it sets.
Track dough temperature obsessively. The ideal final dough temperature after mixing is 24-26°C/75-78°F. If your kitchen is cold, use warm water; if hot, use ice water. A 2°C difference in dough temperature can shift bulk fermentation time by 30 minutes or more. The poke test is your most reliable indicator of proofing: press a floured finger 1cm into the shaped, proofed dough — if it springs back slowly and leaves a slight indent, it is ready; if it springs back instantly, it is under-proofed; if the indent remains, it is over-proofed. For sourdough, maintain your starter at 100% hydration (equal weights flour and water) and feed it 12 hours before mixing for peak activity — the starter should have doubled and just begun to recede. Bake darker than you think. Most home bakers pull bread too early. The crust should be mahogany, not golden — the deep colour signals full Maillard development and the flavour difference is profound. Cool completely on a wire rack before cutting — at least 1 hour. The crumb is still setting as it cools, and cutting early releases steam that makes the interior gummy.
Measuring flour by volume. A cup of flour can weigh anywhere from 120g to 160g depending on how it is scooped, a 33% variance that makes consistent bread impossible. Weigh everything. Under-developing gluten — either through insufficient kneading or too few stretch-and-fold sets — produces bread that cannot hold its shape or trap gas, resulting in a dense, flat loaf. Over-proofing during bulk fermentation (letting the dough more than double) exhausts the yeast's food supply and weakens the gluten to the point that it collapses during baking. Under-proofing produces a tight, gummy crumb with large irregular holes caused by gas forcing its way through an overly resistant structure. Not preheating the baking vessel — a Dutch oven or baking stone must be at full temperature before the dough goes in, or oven spring is lost. Slashing too shallow: score marks must be at least 1cm deep and at a 30-degree angle to direct the bread's expansion; shallow scores seal over immediately and the bread ruptures unpredictably. Adding too much flour during shaping because the dough is sticky — this creates dry, floury seams in the finished loaf. Use a bench scraper and light dusting instead.
