1. 1. Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, baking powder, and salt. Make sure there are no lumps and the ingredients are evenly distributed.

2. 2. Add Wet Ingredients: Pour the unfed sourdough discard and 2 tablespoons of olive oil into the bowl with the dry ingredients.

3. 3. Mix the Dough: Use a sturdy spoon or a spatula to mix everything together until a shaggy dough forms. It will look a bit rough at this stage.

4. 4. Knead Briefly: Turn the dough out onto a lightly floured surface. Knead it gently for about 2-3 minutes until it comes together into a relatively smooth ball. Avoid over-kneading, as this can make the crust tough.

5. 5. Prepare for Baking: Lightly grease a pizza pan or baking sheet with a little extra olive oil. Alternatively, you can line it with parchment paper for easy cleanup.

6. 6. Shape the Dough: Place the dough ball onto the prepared pan. Using your hands or a rolling pin, press or roll the dough out to your desired thickness and shape. Aim for about a 1/4-inch thickness for a classic crust. If it springs back, let it rest for a minute or two, then continue shaping.

7. 7. Add Toppings and Bake: Once shaped, add your favorite pizza sauce, cheese, and toppings. Bake in a preheated oven at 425 F (220 C) for 15-20 minutes, or until the crust is golden brown and the cheese is bubbly and melted. The edges should be slightly crisp.

8. 8. Serve Immediately: Carefully remove the pizza from the oven, slice, and serve hot.
