White pizza: Sliced tomato, onion, mushrooms, cheese, oregano.
Normal Pizza: Reduced and herbed tomato juice from stewed tomatoes, sliced stewed tomatoes, anything including but not limited to mushrooms, olives, hot cactus, capers, ... then cheese and pepperoni. I'm not a big sausage fan.
Temp? I cook mine in a 12 or 14 inch iron skillet. I use the dough made from one pound of flour. 400 ~ 450, usually 400 f for 10 to 15 uncovered, then 15 to 20 with foil on top. Makes a thick, light crust.
All pizza gets olive oil. In the pan, drizzled over top, and a healthy bead laid around the pans perimeter. Result is a oil crust. If there isn't some oil in the pans bottom (1~2 ts) when I remove the pizza I didn't lay the oil in heavy enough.
