Pita is a leavened flatbread made from yeast, water, and flour, and can be cooked by baking, steaming, frying, grilling, and most traditionally, on a stovetop or hot stone; high heat is needed to form the signature "pocket" in the pita. Some pitas are used as wraps, such as in Palestinian shawarma or Greek gyros, while others are flavored with herbs and spices.
