Description
A stiff dough preferment using minimal yeast to develop complex flavors and gluten structure through slow fermentation.
Technical
Hydration levels (50-60%) create osmotic stress that slows Saccharomyces cerevisiae activity while favoring protease and amylase enzyme action, producing maltose and free amino acids while strengthening gluten networks through disulfide bond formation.
Culinary Significance
Provides superior oven spring and open crumb structure in lean doughs while developing nutty, wheaty flavors absent in straight doughs.
