Andrew, do you top and bake the pizza while its still frozen, or do you leave it out until its more or less thawed?
For my pop up I let them defrost. I have baked from frozen for day off snacks, works fine. Longer bake and toppings can over cook if heat is too high. I've also made take and bake pies for friends with still frozen dough that all came out well.
I'm sure the whole thing would work just fine to make a bake from frozen pizza. The Modernist cusine folks have a good process they cover on the latest podcast. Someday, as my operation grows I'll figure out a market to sell it to. It would be a great option for a retail store in the fridge or freezer case.
Good luck.
Andrew
