Functional Profile
Commercial instant yeast is the leavening material in the Roman pizza dough; the Recipe does not specify a sourdough culture.
Handling
Mix the declared 2 g with flour and initial water; preserve the four folds and covered 18 h–24 h refrigeration.
Culinary Use
Bring dough to room temperature and proof until aerated before topping. Do not infer a yeast-and-lactic-acid culture from cold fermentation alone.
