for all those who want to make great homemade pizza, but dont have a pizza/bread stone; i found a trick.
turn your largest cast iron skillet upside down, put it on the lowest rack, then heat the oven as hot as it will go.
normally when i make homemade pizza, i use store bought dough and i grill it. had no charcoal, and decided to wing a pizza dough recipe. it turned out beautifully.
