A pizza stone is a flat, usually round, cooking surface made from materials like ceramic, stone, or cordierite. It is designed to absorb and retain heat, allowing for even cooking of pizza crusts. When preheated in an oven, the stone helps achieve a crispy crust by mimicking the conditions of a traditional pizza oven. Using a pizza stone is simple. You place it in the oven while it heats up, then transfer your prepared pizza onto the hot stone. The intense heat from the stone cooks the dough quickly, resulting in a delicious, evenly baked pizza with a satisfying texture.
