Mix 3 cups of flour and 1 tsp. of salt in a medium sized bowl. Stir in herbs, if using. If using fresh herbs, double the amount to 4 Tbsp.
Mix 1 Cup of water and 1/2 cup of sourdough starter.
Pour the wet mixture into the flour mixture and stir until combined. You may use your hands, if you prefer. The dough will be a bit dry.*
Cover and allow the dough to sit on the counter for 6-8 hours. Ideal temperature for culturing sourdough is between 65F - 70F (18C - 21C).
Uncover the dough once fermented and divide it evenly into 6 or 8 balls for individual-sized pizzas, or 2 balls for medium-sized pizzas. Allow these to rest for a few minutes while you prepare the pans.
You can use any pan or baking sheet you have available, though metal is preferred. Cover the pan in parchment paper for ease of use and clean up, or lightly oil with olive oil. If you're using a cast iron or stoneware pizza pan, be sure to preheat it with the oven to avoid cracking.
Roll out each ball for the preferred size. You can use a pastry roller, but I usually just use my hands. The finished thickness should be around 1/4". Dimple the dough with your fingertips to prevent puffing up while baking. This also produces subtle divots for sauce to rest inside.
Place the pizza dough on the prepared sheets and either set to rise until doubled for thicker curst pizza, or immediately place in the oven for thin crust pizza. Unless using a cast iron or stoneware pan, you can place the pizza dough in a cold oven.
Bake at 425F/218C for about 10 minutes or until lightly browned. If your oven runs hot, check the crusts at around 5 minutes. If your oven runs really hot, bake the crusts at 400F/204C.
Once pre-baked, cool to touch and then load up the crusts with pizza sauce, cheese, and other favorite toppings.
Return to the oven and place under broil to melt the cheese. This can take 5-10 minutes depending on the heat of your broil setting. Watch it and remove when your cheese looks perfectly melted.
Allow to cool for at least 5 minutes to set the cheese.
