I have had mixed success with pizzas. Either they come out great or they burn. Here is my process:
-XL Egg with plate setter legs down and pizza stone on top of plate setter
-Heat the egg up to 550-600, let stabilize for 20 mins or so
-Cook pizza for 8-10 minutes
Last night using homemade dough the crust burnt in less than 5 minutes.
