Gluten — the protein network formed by the hydration and mechanical development of gliadin and glutenin in wheat flour — is the structural foundation of all wheat-based preparations. Modernist Cuisine's treatment provides precise control parameters: protein percentage, hydration, mixing time, rest periods, and the specific additives (ascorbic acid, vital wheat gluten, diastatic malt) that modify gluten behaviour.
- **Protein content and gluten strength:** - Bread flour: 12–14% protein — strong gluten for yeasted bread, pizza. - All-purpose: 10–12% — moderate gluten for pastry and pasta. - Cake flour: 7–9% — minimal gluten for tender cakes. - Pasta (semolina): high protein but different protein type (high gluten but less elastic than bread flour). - **Hydration effect:** More water = more extensible gluten. A 65% hydration bread dough has different handling properties from the same flour at 80%. - **The autolyse:** Mixing flour and water alone (no yeast, no salt) and resting for 20–30 minutes before kneading — the gluten network partially develops without mechanical work. This technique (developed by Raymond Calvel) produces a more extensible, less tear-prone dough. - **Salt's role:** Salt tightens the gluten network — doughs made with salt earlier in the process are stiffer. Adding salt after initial mixing produces a more extensible initial network.
