Provel is American cheese, produced with a combination of many kinds of cheese, mainly cheddar, swiss and provolone. This pasteurised processed cheese has a low melting point and appears gooey and buttery at room temperature. It is a mainstay in many St. Louis-style pizza and cheese soup dishes.
Provel was first made by Costa Grocery in collaboration with the Hoffman Dairy Company of Wisconsin, specifically as a topping for St. Louis-style pizza. People wanted a melting cheese that could easily break with the crust and melt in the mouth. Provel has retained its popularity in St. Louis and is often manufactured and sold in and around this area. Provel is either available in loaf form or rope form.
