Is the bottom of your cast iron pan smooth enough to turn it upside down for baking the pizza?
I'm not sure what you mean by turning it upside down. But, no, it's still a young pan with a thin seasoning on it so far. Same pebbly texture as from the store. I have thought about taking to work to see if they can smooth it out.
I used plenty of grease in it for the pizza, though, and it slid right out. Last night I cooked Steak Sandwich stuff right in there. Meat, onion, green peppers, mushrooms. Didn't stick a bit (ok, well the cheese stuck on one spot, but I let it cool before cleaning it.)
