The KPBS-22.5S is a 3/16" thick round stainless baking steel used to provide higher dome temperatures in your KettlePizza oven. The steel radiates heat rapidly and provides a very hot ceiling for getting quick crisping of the top of your pizza. Used in conjunction with the KettlePizza ProGrate, users can expect cooking cycle times in the 4-5 minute range. Openings on the side allow adequate oxygen flow and allow easy refueling. Use the KP Baking Steel by itself in your kettle grill as a skillet! Cook breakfast, veggies or sear steaks and burgers. A very versatile product!
