Detroit-style pizza is believed to have been first created in the late 1940s at a place called Buddy's Rendezvous, which later became Buddy's Pizza. Gus Guerra, the owner, is often credited with its creation. One of the defining characteristics of Detroit-style pizza is its crispy, thick crust, achieved in part by baking the pizza in blue steel pans, which were originally used by automotive factories as utility trays. These pans are believed to be responsible for giving the crust its unique caramelized cheese edge. Detroit-style pizza has a distinct layering method. Cheese (often brick cheese) is placed directly on the dough, followed by any additional toppings, and then the sauce is ladled on top. This layering technique ensures the crust doesn't get soggy from the sauce and retains its crispy texture.
I prefer using glass tray, which allows nice crust and offers better release pizza after baking.
