Discover how autolyse improves gluten, softness, and crumb in brioche dough.
1 Answer
Autolyse improves brioche texture by allowing flour to fully hydrate, developing gluten and resulting in a softer, more extensible dough and a more tender crumb.
Detailed Explanation:
Autolyse is a resting period in bread making, specifically beneficial for enriched doughs like brioche. It involves mixing only the flour and water (or sometimes just the flour and a portion of the water) and letting it rest for a period, typically between 20 minutes and an hour. During this time, several key processes occur:
-
Flour Hydration: The flour particles fully absorb the water. This complete hydration is crucial because it allows the gluten proteins (gliadin and glutenin) to begin aligning and forming gluten strands. This initial gluten development happens without the mechanical action of kneading.
-
Enzyme Activation: Enzymes present in the flour, such as amylase and protease, become active. Amylase breaks down starches into simpler sugars, providing food for the yeast later on. Protease breaks down some of the gluten proteins, which paradoxically, makes the dough more extensible and less resistant to stretching. This contributes to a more tender crumb in the final brioche.
-
Simplified Kneading: Because the gluten network has already begun to form during autolyse, the subsequent kneading process is significantly easier and shorter. This is important for brioche, as over-kneading can lead to a tough texture.
The result of autolyse is a dough that is smoother, more extensible, and easier to work with. In brioche, this translates to a final product with a lighter, more tender, and more evenly textured crumb. The improved gluten development also contributes to better volume and a more appealing rise.
Pro Tip:
When autolysing brioche dough, hold back the butter and eggs until after the autolyse period. Adding these ingredients too early can inhibit gluten development and reduce the effectiveness of the autolyse.
