My favorite recipe is from a friend from KY. 1 cup cornmeal, about 3/4 cup flour, 1 tsp baking powder, 1/2 tsp salt, 1/2 tsp baking soda. Stir this together. Add up to 1 tbsp sugar or none at all. We prefer brown sugar. Beat an egg and add it. Stir in buttermilk until it looks good. Usually 3/4 to 1 cup. I don;t measure it. Preheat an iron skillet in the oven at 375. Add some bacon grease or butter. Pour in batter, bake about 22 to 25 minutes. Test with a toothpick.
I have also made it substituting cornmeal for the flour because I was out.
