What is typically the base ingredient for making a pan pizza?

The foundation of a pan pizza is indeed based on regular dough. This type of dough is specifically designed to create a thick, fluffy crust that rises beautifully in the deep-pan structure of the pizza. The methods used to prepare regular dough allow for a light and airy texture, which is a distinguishing feature of pan pizza. Regular dough typically contains ingredients such as flour, water, yeast, and salt, allowing it to rise effectively and create the desired crust thickness and chewiness.

In contrast, the other options represent different styles or types of crusts that do not fit the traditional pan pizza definition. Cracker crust tends to be thin and crispy, which contrasts with the thick, soft characteristics of pan pizza. Whole wheat dough, while a healthier alternative, is not the standard choice for a classic pan pizza. Flatbread is also not suitable, as it refers to a very thin and typically unleavened crust, which does not have the same texture or depth as a pan pizza's regular dough. Thus, regular dough is the ideal choice for achieving the authentic deep-dish experience associated with pan pizza.
