Preheat the oven to 450°F. Place a pizza stone or baking sheet in the oven to preheat as well.
In a large bowl, combine water, yeast, and sugar and let sit for 5 minutes, or until bubbly.
Add salt and oil, then mix in flour 1 cup at a time with a wooden spoon until combined and the dough is soft and slightly sticky. Knead for about 3 minutes (dough will be sticky and will stick to your hands).
Cover the dough with a tea towel and let rise at room temperature for 30–45 minutes.
This dough makes four 12-inch pizza crusts. Divide dough into four pieces and roll each out onto a floured surface to about ½ inch thick.
Sprinkle cornmeal onto a pizza peel and, working with one crust at a time, transfer the rolled-out dough to the peel. Brush with olive oil and poke with a fork a few times to eliminate bubbling while baking.
Use the peel to transfer the crust to the preheated pizza stone, or pan, and blind bake for 6–8 minutes. Remove from the oven, add sauce, cheese, pizza seasoning, pepperoni, and any other desired toppings, and bake for 8–10 more minutes.
