Step 1

Place a 10-inch cast iron skillet in a cold oven. Preheat oven to 400 degrees F, leaving the skillet in the oven while it heats.

Step 2

Meanwhile, whisk together the flour, cornmeal, sugar, baking powder and salt in a large bowl.

Step 3

Add the buttermilk, egg and oil. Stir to combine.

Step 4

When the oven has come to temperature, pour about 2 tablespoons of oil into the hot skillet (or enough to thoroughly coat). Use a brush to evenly spread the oil. Pour batter into the hot, greased skillet. Bake for 20-25 minutes, or until golden brown and a toothpick comes out clean.
