Lovely looking pie! I’ve been doing cast iron pizzas for some time now. You can cut your cooking time down by 10-15 min if you do the following:
Start cooking on stove: burner on high for ~4-5 min to set the dough. When you first turn the burner on, also turn on the broiler.
Toss it under the broiler for another ~5min or until your cheese crisps up just the way you like it.
The higher heat of the stove and broiler (even though it’s not at the same time) mimics the super hot pizza ovens a bit better (imo).
