Instructions
Place your cast iron skillet in your oven and preheat your oven to 425°F.
Allow your cast iron skillet to get hot by leaving it in the oven 10 minutes beyond preheating temperature being reached.
While your cast iron skillet is heating, combine the sourdough discard, baking soda and optional spices/herbs.
Remove your cast iron skillet and add the olive oil, being sure to coat the inside of the skillet well.
Add the discard/baking soda mixture to the hot cast iron skillet. It will sizzle and start to cook on the bottom. Spread the mixture around in the skillet and up the sides.
Bake for 7-8 minutes. You are looking for the pizza crust to be firm but not overcooked.
Remove from oven and add your toppings.
Return to the oven and bake an additional 5-8 minutes, or until your toppings are melted/warm.
