Gluten development
The process of building the stretchy, elastic protein network in dough that traps gas and gives bread its structure.
Gluten development is the process by which two proteins naturally present in wheat flour, glutenin and gliadin, combine with water and physical movement to form a stretchy, interconnected network. This network is what allows dough to stretch without tearing and to trap the carbon dioxide produced during fermentation, which is what makes a loaf rise instead of staying flat.
In sourdough baking, gluten development usually comes less from vigorous kneading and more from a combination of time, an autolyse rest, and repeated stretch and fold sessions during bulk fermentation. This gentler, time-based approach works especially well for the wetter, stickier doughs common in sourdough, where kneading by hand would be difficult and folding does the job with far less effort.
No special equipment is required to develop gluten by hand, though a large bowl with room to fold makes the process easier to manage. A common mistake is judging gluten development purely by how long a dough has been mixed or folded rather than by how it actually feels and stretches, since flour type, hydration and temperature all change how quickly gluten builds. The windowpane test is a more reliable check than time alone.
