Autolyse, a resting period for flour and water before adding yeast, improves white bread texture by hydrating the flour fully, developing gluten, and enhancing extensibility, leading to a softer, more open crumb.
Autolyse is a simple yet powerful technique in bread baking that involves mixing flour and water and letting it rest for a period, typically between 20 minutes and an hour, before adding the yeast and salt. This resting period allows the flour to fully hydrate. When flour is properly hydrated, the gluten proteins begin to align and develop naturally, without the need for excessive kneading. This results in a dough that is more extensible, meaning it can stretch further without tearing. The enzymes present in the flour also begin to break down starches into simpler sugars, which contributes to the bread's flavor and also makes the dough more pliable. The final result is a white bread with a more open crumb structure, a softer texture, and improved overall quality. By allowing the gluten to develop passively, you reduce the need for vigorous kneading, which can toughen the dough and lead to a less desirable texture.
When autolysing, reserve a small amount of water (around 10-20%) to add later with the salt. This helps to control the gluten development and prevents the dough from becoming too sticky during the initial mixing phase.
