How many high can a stack of pans containing pizza dough reach during proofing?

The correct answer is that a stack of pans containing pizza dough can reach up to 5 high during proofing. This is significant because during the proofing process, the dough needs adequate space for expansion and fermentation. Stacking the pans too high can impede proper airflow and prevent the dough from rising effectively. A stack of 5 pans strikes a balance between maximizing space efficiency and allowing each layer of dough the necessary room to expand properly. It ensures that the dough receives enough warmth and moisture, which are essential for the yeast activity, leading to an optimal rise before baking. This understanding helps in managing the proofing process effectively in a pizza-making environment.
