Preheat the oven to 550 degrees with a pizza stone or baking sheet in the oven.
In the bowl of a stand mixer, bloom the yeast in warm water by lightly mixing the yeast into the warm water. After a few minutes the yeast should look bubbly.
Next, mix in sourdough discard, honey, salt, oil, flour and cornmeal in a stand mixer. Using a dough hook, knead for 8-10 minutes or until a firm dough ball forms.
Cover the dough and let it rise for about 30 minutes.
Divide dough into two pieces for medium sized pizzas, or skip this step to make one large pizza.
Sprinkle a tablespoon of cornmeal on a piece of parchment paper and set to the side.
Roll out the dough to your desired thickness. The dough will continue to rise, so for a thick crust pizza roll the dough out to about 1.5 inches thick.
Place the rolled out pizza crust on the parchment paper with cornmeal. Add pizza sauce and desired toppings.
Take out the preheated pizza stone from the oven and carefully slide the parchment paper with the pizza on to the preheated stone.
Bake until the crust is golden brown and cheese is melted (8-12 minutes depending on oven).
