To a medium bowl, add starter, olive oil, and egg. Whisk to combine.
150g grain-free sourdough starter, 15g extra virgin olive oil, 1 large egg
Add the almond flour, tapioca flour, and salt. Combine using a dough whisk until the flour has absorbed the liquid.
88g almond flour, 132g tapioca flour, 5g salt
Gradually add the water, stirring after each pour until you reach a smooth, but not runny texture. You may not need all of the water.
30g-40g warm water
Once combined, smooth the top of the dough with a rubber spatula and cover the bowl with a lid. Let the dough sit at room temperature for 2 hours and then transfer to the refrigerator overnight.
When you are ready to bake the pizza crust, place a pizza stone in your oven and preheat it to 450 degrees F. Set a timer for 1 hour.
When your oven is fully preheated, take the dough out of the refrigerator. Rub some olive oil on a piece of parchment paper. Then, cut the dough in half with a butter knife. Take out half of the dough and form into a ball then flatten with your hands. Place the dough on the piece of parchment paper and press out into a 9 inch round, making sure to leave an outer crust.
Transfer the dough, still on the parchment paper, to a pizza peel. Cut any excess parchment paper and then transfer to the hot pizza stone. Par-bake for 6-8 minutes.
Once the crust is par-baked, add your favorite toppings and continue baking for an additional 10-12 minutes. Slice and serve hot!
