A tender, slightly tangy cornbread baked in a cast iron skillet. The sourdough discard adds moisture and flavor.

Preheat oven to 400°F (200°C). Place a 10-inch cast iron skillet in the oven to heat.
In a large bowl, whisk together the cornmeal, flour, sugar, baking powder, baking soda, and salt.
In a separate bowl, whisk together the sourdough discard, eggs, buttermilk, melted butter, and honey.
Add the wet ingredients to the dry and stir until just combined. Do not overmix.
Carefully remove the hot skillet from the oven. Add the 2 tbsp butter and swirl to coat the bottom and sides.
Pour the batter into the hot, buttered skillet. It should sizzle.
Bake for 25-28 minutes until golden on top and a toothpick comes out clean.
Let cool in the skillet for 5 minutes. Slice into wedges and serve warm with butter and honey.
