Heat-resistant to 800 degrees, this reversible ceramic stone is a natural for grilling or baking crispy pizza or tortillas. Reversible stone has a ribbed side for burgers, steaks and poultry. Even heat distribution cooks without hotspots, duplicating the effect of a brick-lined pizza oven. The more the stone is used, the more it will enhance the flavor of foods. With use, the stone will darken naturally over time. Cleaning it with hot water and a grill brush while still hot will preserve the seasoning; a more thorough cleaning with hot water and soap or in the dishwasher will require re-seasoning with vegetable oil spray.
