While researching a home hack of this now-iconic recipe, I discovered an unexpected technique that I hadn’t seen in other deep dish recipes. Employees told me the pizza crusts are partially cooked each morning to cut down on the wait time for customers. Before the restaurant opens each day, cooks press the dough into a pan and then sprinkle it with a little shredded cheese. The shells are then partially baked and set aside. Later, when an order comes in, the pizza is built into one of the par-baked crusts and finished off. This way customers get their food faster, and the tables turn over quicker.
