For Weber Kettles 22.5" & 18.5"
Everyone wants to cook pizza on their grill! Traditional grills, however, are not suited for cooking pizza. Pizza needs high heat and constant temperature to cook properly. This is difficult to achieve in a regular grill because the constant opening/closing of the grill top leads to massive variation in cooking temperature. The common result is a well done bottom and under cooked toppings.
We solved this problem by designing a stainless steel sleeve that fits between the kettle grill bottom and top creating a cooking chamber. There is an opening in the front that allows access to the chamber. The heat comes up from the back of the kettle, along the rear of the cooking chamber and over the top exiting the front opening. This creates a "consistent" heat loss that is forces heat over the top of the pizza ensuring a properly cooked top. A door is not necessary and the product can maintain consistent temperatures upwards of 750 degrees F with a base of charcoal and hard wood.
