Pre-heat oven to 450°
Sprinkle bottom of cast iron skillet with a pinch of fine ground corn meal or rice flour.
Place the dough on a floured work surface and cut it in half. If you are making 2 crusts, place both pieces on a floured work surface, cover with a tea towel and let rest for about 10 minutes. After 10 minutes, keep one dough covered (if using) and gently knead the other dough for about 4 minutes until smooth. If making 2 crusts, repeat with second ball of dough.(NOTE: If you are making only one crust, wrap the other piece in plastic and store in the fridge for up to 5 days. Freeze in a freezer bag for up to 3 months.) After kneading, roll out dough ball to the size of your skillet. Approximately a 12-inch round.
In one decisive action, lift dough like a boss and lay it into the skillet. Gently press it to the bottom of the skillet and push just a little way up the sides of skillet.
Brush the dough with olive oil.
Spread homemade pizza sauce (if using) or store bought sauce onto the dough in the skillet.
Sprinkle the cheese on top of the sauce.
Add toppings.
Drizzle a tiny bit of olive oil around the edge of the pizza so that it seeps in between the dough and the sides of the skillet. This gives crust a crispy golden crunch and helps it come out of the pan easier.
Bake pizza in the oven for 15 minutes or until golden brown.
