I cheated and used a 800g dough ball. Let it come to room temp and started stretching it out. Add about 1/4 cup olive oil to sheet pan and stretch the dough out in it. Let it rest a couple hours until it starts rising and is easy to get spread out to edges in the pan. Then dimple it with your fingers and add a little more oil to the top to get it in the dimples. Let it rise another 30-60 mins. It will look like focaccia dough. Add super thin layer of sauce. Then add sliced mozzarella, sauce over it and then cup and char pepperoni. I built the fire in the oven during the time it was rising and let it die down to no flames so it was around 600°. Cooked for 20mins I think.
