 The pizza was developed in 1946 at Buddy's Rendezvous, a former blind pig owned by Gus and Anna Guerra located at the corner of Six Mile Road and Conant Street in Detroit.Sources disagree whether the original Sicilian-style recipe was based on Anna Guerra's mother's recipe for "sfincione" or on a recipe from one of the restaurant's employees, Connie Piccinato.The recipe created a "focaccia-like crust" with pepperoni pressed into the dough to "maximize the flavor penetration".
