The Chicago-style "stuffed" or "deep-dish" pizza begins with a simple, often very thick, crust in a deep round pan. The bottom of the crust is lined with ingredients, such as pepperoni or any other pizza topping while the sides rise to the top of the pan. A well prepared stuffed pizza generally has much higher topping density than any other type of pizza. Mozzarella cheese is added atop the meats, vegetables, or whatever other topping are used. Then, an additional layer of dough is added over the cheese. This second layer of dough is secured to the primary crust. At this stage in the preparation, the thin dough top should have a rounded, domed appearance, with the center rising almost as high as the primary crust, and the sides appreciably lower, to act as a reservoir for the sauce.
