Whisk sourdough starter into the water. Pour flour over the top and sprinkle salt evenly over the flour. Using a stiff spatula mix until well combined. Cover bowl with a moist towel and let dough rest for 15 minutes.
Using a plastic bench scraper, scoop dough onto a well floured surface. Knead dough until stiff and elastic, about 3-4 minutes. Divide dough into 3 equal pieces for large pizzas. Roll each piece into a ball. Place dough balls onto a sheet pan lined with parchment. Cover with a moist towel and refrigerate overnight.
When ready to make the pizza, let dough sit on counter for 30 minutes. Using your hands, shape each ball on a well floured surface, into rounds. Top with your favorite toppings and bake at 500 degrees for 10 –12 minutes.
Notes
Pizza dough can be stored in refrigerator for up to 3 days. Keep in a plastic bag or covered container using parchment paper to avoid dough from sticking to surface.
