Sourdough Cornbread
Ingredients
- ¾ cup (90 g) gluten-free all-purpose flour
- 1 teaspoon (3 g) xanthan gum (see notes)
- ¾ cup (100 g) gluten-free cornmeal (see notes)
- ¼ cup (50 g) granulated sugar
- 2 teaspoons (8 g) aluminum-free baking powder
- ½ teaspoon (3 g) kosher or fine sea salt
- ¾ cup (180 mL) whole milk, room temperature (see notes)
- ¼ cup (60 mL) avocado oil (or neutral oil of choice)
- 1 large egg, , room temperature
- 1 cup (265 g) sourdough discard
Instructions
- Preheat the oven to 400°F and spray an 8x8-inch square baking pan with gluten-free nonstick spray or grease with butter.
- In a medium bowl, whisk together the flour, xanthan gum, cornmeal, sugar, baking powder, and salt. Set aside.
- In a large bowl, whisk together the milk, oil, and egg, then whisk in the sourdough discard.
- Add the dry ingredients to the wet ingredients and mix until completely incorporated.
- Transfer the batter to the prepared baking pan and gently smooth out the top and make sure the batter is evenly distributed in the pan. Bake for 20-24 minutes or until done.
- Serve warm or at room temperature with honey butter or spread with butter and a drizzle of honey.
Notes
- Omit the xanthan gum if your flour blend already contains it.
- For best results, use a finely ground cornmeal. If yours is coarse, run it through a food processor to make it a bit finer.
- For dairy free, use Silk Heavy Whipping Cream Alternative for the best whole milk substitute. You can also use unsweetened coconut milk beverage.
- Store leftovers at room temperature in an air-tight container up to 2 days. Leftovers can also be frozen for up to a month in a freezer-safe bag.
