The Dough Handbook

This handbook records how a handful of flour becomes bread: what protein builds, what water changes, what fermentation adds, and what the oven finishes. Each entry gives the short answer first, then the working detail — ranges, signs, and causes. Nothing here is for sale; the pages exist only to be read.

What does flour do in a dough?

Flour supplies both scaffold and feed: protein builds the gluten network, starch absorbs water and feeds the yeast.

Wheat flour is mostly starch, but its character comes from two proteins, glutenin and gliadin. Wetted and worked, they link into gluten — an elastic web that traps gas. Bread flours carry roughly 12–14% protein; cake flours about half that.

Ash, the mineral residue measured after milling, marks how much of the grain's outer layers remain; European type numbers encode it. Higher-extraction flours ferment faster and taste fuller, but rise less high.

Starch works quietly. Intact granules absorb water slowly; starch damaged in milling absorbs fast and is broken by enzymes into sugars that feed fermentation — one reason two flours of equal protein behave differently.

  • Bread flour: about 12–14% protein, built for gas retention
  • All-purpose flour: about 10–12%, a workable middle
  • Cake and pastry flours: about 7–9%, milled for tenderness
  • Whole-grain flours: higher protein on paper, but bran cuts the network

Terms this handbook relies on

Gluten
The elastic protein network formed when wheat flour's glutenin and gliadin are hydrated and worked. It traps fermentation gas and gives bread its chew.
Hydration
Water expressed as a percentage of flour weight. Sixty percent hydration means 60 grams of water for every 100 grams of flour.
Baker's percentage
A recipe convention in which flour is always 100% and every other ingredient is written as a share of the flour weight, so formulas scale and compare easily.
Bulk fermentation
The first rise, done before dividing, when most gas and flavour develop. Its length is set by dough temperature and yeast quantity.
Autolyse
A rest of flour and water before salt and leavening are added. It hydrates the flour fully and shortens the mixing needed afterward.
Oven spring
The rapid expansion of a loaf in the first minutes of baking, driven by expanding gas and a final burst of yeast activity before the heat kills it.

Questions dough is asked most

Why is my dough so sticky?
Sticky dough usually means high hydration, underdeveloped gluten, or both. Wet your hands instead of adding flour, give the dough a rest, and check that the water percentage suits your flour.
Can plain all-purpose flour make good bread?
Yes — most everyday loaves bake well at 10–12% protein. Expect slightly less chew and a little less rise than bread flour, and hold back some water at first.
How do I know bulk fermentation is finished?
Look for a dough that has clearly risen, shows bubbles at the surface, and jiggles when the bowl is shaken. Time is only a guide; dough temperature decides the real pace.
Why did my loaf turn out dense?
Density almost always traces to under-fermentation, too little water, or a weak gluten network. Give the dough more time, confirm the flour's protein, and handle it gently once it is full of gas.

How this record is kept

Each entry is compiled from standard baking-science references and long-established practice, then cross-checked for internal consistency. Ranges are given as working values, not absolutes, and no claim rests on a single proprietary source. Nothing on these pages is sponsored or sold.

Sources and basis

The handbook draws on widely taught bread science and standard reference works; no single source is privileged, and no commercial ties exist.
