How to bake it
Twelve minutes, from frozen
Do not thaw. Do not use a pan. The base is already baked, so all the oven has to do is finish the cheese and crisp the bottom.
Heat to 230 °C
Fifteen minutes of real preheat. A cold oven steams the crust.
Straight on the rack
Middle rack, no tray, no parchment. Twelve minutes.
Rest two minutes
Cut after it settles so the cheese stays where it landed.

Three things worth adding
Rocket and shaved grana on the Prosciutto, after the oven, never before.
A thread of chilli oil on the Diavola.
Torn basil on the Margherita as it rests.
