Scratching your head? Let us explain: detroit pizza has an extra-thick crust thats crispy on the outside and pillowy on the inside and a top thats covered from edge to edge with melted mozzarella, slices of pepperoni and a healthy shake of parmesan. Where the cheese spills over the edge, it bakes into the crust, so that signature crust gets crisper still when baked. Rumor has it, auto workers created this style by baking their pies in deep metal trays cast off from the assembly line. While you can skip the industrial trays here, bettys version is made in your 13x9-inch pan; this recipe stays true to the originals no-nonsense approach. Made with five ingredients, this pizza is ready to eat in 35 minutes. But be warned, its likely to disappear even quicker.
