How to Make Fluffy Skillet Sourdough Discard Cornbread
Step 1: Preheat the Oven and Skillet
Preheat your oven to 400°F. Place a 10-inch cast iron skillet in the oven for 10-15 minutes with 1 tablespoon of butter or bacon fat.

In a large bowl, whisk together the yellow cornmeal, all-purpose flour, salt, and baking powder until well combined.

Follow the recipe instructions to mix the wet and dry ingredients, but hold off on adding the baking powder. Once combined, cover the batter with plastic wrap or transfer it to an airtight container and place it in the refrigerator overnight.
