New York and Chicago get a lot of attention for their pizzas, but Detroit’s spin on the pie should not be overlooked. The square Sicilian-style pizza — which is about to celebrate its 70th anniversary — was introduced at Buddy’s, a neighborhood tavern at Six Mile and Conant in the heart of the city. To create the style, deep-dish dough is double-stretched daily, resulting in a thick-yet-airy square, and is topped with Wisconsin brick cheese, with sauce (and optional pepperoni or peppers) tucked underneath the cheese to keep the flavor without the charring.
