1. Place a pizza stone, cast iron skillet, or heavy-duty baking sheet in the oven, and preheat it to 500F. Place the tapioca starch in a mixing bowl and set aside.
2. As the oven heats, add the milk, 2 T of the butter, and ½ tsp salt to a small saucepan and heat over medium heat until just about to boil, then pour it into the mixing bowl. Mix with a spoon until incorporated into the starch, then set aside for 5 minutes to cool.
3. Add the nutritional yeast, ½ tsp rosemary, and the oregano and white pepper to the dough, then knead together to incorporate everything. Carefully remove the hot pizza stone from the oven, then (again, carefully!) spread the dough over the stone, to about 1/4″ thickness. It doesn’t have to be pretty.
4. Drizzle the 2 tsp of melted butter over the dough and sprinkle on the remaining ½ tsp of rosemary and the ¼ tsp pink salt, then place in the oven. Bake until crispy and firm to the touch for 8-10 minutes.
5. Serve warm and dip in olive oil if desired.
