Provel cheese is a popular white cheese that is very popular in St. Louis, Missouri. It is made of a composite of cheeses, including cheddar and swiss. Provel cheese is very soft with a gooey and almost buttery texture. Provel's low melting point makes it the key ingredient in St. Louis style pizza, most notably Imo's Pizza. It is also common on salads and on chicken. While very popular in the St. Louis area, Provel cheese is almost unheard of elsewhere.
