Distinct regional pizza variations exist within the United States, notably two prominent examples originating from major Midwestern cities. One features a deep-dish construction with a characteristically high crust, creating a vessel for substantial amounts of cheese, sauce, and toppings. The other presents a square or rectangular shape, a thick, airy crust, and a caramelized cheese edge resulting from baking in steel pans.
These regional specialties represent culinary innovation and adaptation to local ingredients and preferences. Their development reflects the cultural identity of their respective cities and the resourcefulness of pizza makers. They have become significant aspects of regional cuisine, attracting tourists and inspiring countless adaptations and interpretations worldwide.
