A specialized baking implement, characterized by its depth and often seasoned cast iron or non-stick construction, is essential for creating a specific regional pizza variant. This implement facilitates the creation of a pie with a tall, bread-like crust and ample space for generous layers of cheese and toppings. The substantial depth distinguishes it from standard pizza baking sheets.
This deep form factor is critical to the structural integrity and culinary characteristics of the pizza it produces. It allows for the extended cooking times necessary to fully bake the crust and melt the substantial volume of cheese. The design contributes to a textural contrast between the crisp, slightly fried crust and the soft, molten interior. Historically, its design evolved to accommodate the preferences of pizza consumers in a particular Midwestern city.
