Pre-ferment: It is a separate dough that is made first and then added to the final dough mixture.
Ingredients: It consists of flour, water, and a small amount of yeast.
Fermentation: It ferments for a long period, often 12 to 48 hours, which develops flavor and structure.
Benefits: Using a biga results in a more aromatic, flavorful, and porous bread or pizza.
