Description
A yeast-leavened pre-ferment that improves dough elasticity and flavor development.
Technical
Hydration levels typically range from 60-100%, allowing partial gluten development and microbial activity. The sponge method produces organic acids (acetic, lactic) and CO2 through Saccharomyces cerevisiae fermentation.
Culinary Significance
Creates lighter crumb structure in bread while reducing kneading time.
