The Big Green Egg Pizza & Baking Stone is a versatile piece of cookware for baking a variety of recipes from pizzas to breads to desserts. The stone distributes heat for even baking and browning and the ceramics pull moisture from the outer surface of the dough for brick oven crustiness. The Pizza/Baking Stone retains heat, so your foods stay hot longer. (5 sizes 10″, 13", 15", 16″, 18″)
