Preheat oven to 425°F and place an 8-inch cast iron skillet with bacon grease or oil inside to heat.

In a bowl, mix cornmeal, flour, egg, and buttermilk until smooth.

Carefully add some of the hot grease to the batter and stir.

Pour batter into the hot skillet and bake for 15-18 minutes until golden brown.

Let cool slightly, then serve warm with butter or honey.
