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 typically made without yeast, giving it a crisp texture. The pizza is usually cut into squares or rectangles 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.
