When I make pizzas, I usually assemble each on a sheet of parchment. When I bake, I slide the peel under the parchment and pizza and it goes in and out of the oven easily. I ran out of parchment yesterday and was making pizza. I tried flouring a cookie sheet upside down and making the pizza on that so I could slide the peel below but if you leave it sitting any period of time, the dough absorbs the flour and it still sticks. Is there an easier way to assemble all the pizzas at once, if you don't have parchment paper? Does corn meal work better? I also have so much burnt flour in the oven now, from the excess. Any way around this?
