Add all ingredients to a large mixing bowl. Combine well, using a heavy duty spoon or dough whisk. The dough should look rough and shaggy, and feel soft and sticky. Turn the dough out onto a lightly floured countertop. Knead the dough for about 3 minutes, until smooth and tacky (but not sticky).
Return the dough to the bowl, cover with a damp towel (or plastic wrap if you live in a dry area) and and let rise at room temperature or a warm area 4-12 hours (see chart in notes) to ferment.
When the dough has doubled in size, punch it down in the bowl and flip it over. Cover the bowl with plastic wrap again and refrigerate. About 1 hour before you want to bake your pizzas, remove the dough from the fridge.
To Shape the Sourdough Pizza Crust
Lightly flour your work surface. Using a bench scraper or sharp knife, cut the chilled dough into 2 equal pieces for large pizzas, or 4-6 pieces for individual pizzas. Let dough rest at room temperature for one hour. Meanwhile, prepare your pizza toppings and preheat your oven to 450ºF. See notes below about using pizza stones or cast iron skillets for baking.
Shape your pizza crusts by hand, flattening the dough with your palm, then pressing with your fingers to stretch it out, leaving a 1" thick border at the edge. For individual sourdough crusts shape to 10-12 inches in diameter and large to 14 inches in diameter; Add sauce and your favorite toppings. Bake individual sourdough pizzas for 12-15 minutes, and large for 15-20 minutes.

Notes
FOR GRAMS MEASUREMENTS click on the METRIC tab above ingredients.This recipe uses a discard or unfed sourdough starter, which means one that was fed 12-24 hours before starting the recipe. Our recipe does not use a starter that's at its peak when mixing the dough. A 100% hydration sourdough starter works best for this recipe.I recommend using a clear glass mixing bowl for fermentation (rising). This allows you to see the activity on the dough's top and bottom. Often, the bottom of the dough will show a lot of activity, reassuring you that it's properly fermented.Bulk Fermentation Rising guidelines:Rising times will vary according to your room temperature and humidity:
80ºF about 4-5 hours
75ºF about 6-7 hours
70ºF about 8-9 hours
For temperatures under 70ºF it can take up to 12 hours or more
Tips for keeping dough warm during colder months:
Place the bowl in the oven with the door closed and light on to create a slightly warmer climate without actually turning the oven on.
Use a heated mat (like those used for germinating seeds) for rising.
Use the "proof" setting of your oven (I set mine to 85ºF) and set a timer. This will speed up the rising process, so check it at 4 and 6 hours.
If there is a sunny room in the house that stays warm, keep the dough covered in that area.

To prevent food poisoning from undercooked foods, be sure to pre-cook any meat toppings before adding them to your pie. We use our microwave.
Baking on a pizza stone or cast iron griddle promotes a better rise and crispier sourdough pizza crust.
Baking Instructions:We prefer to oven bake pizzas on a pizza stone or cast iron. Flip large skillets over and use the bottom (so you can slide the pizza on and off) or use a flat cast iron griddle. Preheat pizza stones and cast iron by placing in a cold oven and let it preheat to 450°F. Make Ahead Instructions:Freeze unbaked crusts or unbaked assembled pizzas: see our post on freezing pizza dough.Nutritional facts are for 1 slice of crust without sauce or toppings because of the ingredient variations.
