Combine water, sugar, sourdough starter, olive oil, and salt.
Add enough flour to form a nice soft dough (you might not need all ten cups).
Knead until elastic and smooth (use the windowpane test if you’re not sure).
Oil a large bowl and place the dough inside, turning it to coat all sides so it doesn’t stick.
Refrigerate the dough for six hours (or overnight).
When ready to bake, preheat the oven to 350°F.
Dust your work surface with flour and roll out the dough.
Place the dough onto a baking sheet and prick all over with a fork (this is to prevent large bubbles from forming).
Bake for 8 minutes. Remove from the oven and increase the oven temperature to 425°F.
Brush the crust with additional olive oil, and pizza sauce. Add cheese and your favorite toppings. Bake at 425°F until bubbly and slightly brown (about 5-10 minutes depending on toppings).
