St. Louis Style Pizza is a unique type of pizza that originated in St. Louis, Missouri. It features a thin, cracker-like crust that is made without yeast, resulting in a crisp texture. The pizza is typically cut into squares rather than traditional wedges, making it easy to share. Another distinctive characteristic of St. Louis Style Pizza is its use of Provel cheese, a processed blend of cheddar, Swiss, and provolone. This cheese melts smoothly and has a tangy flavor, which sets it apart from the more common mozzarella used in other pizza styles.
