Instructions:
Preheat oven to 425° F.. Put shortening in a 10-inch cast iron skillet and place in the preheating oven while making batter.
In a mixing bowl, combine cornmeal, flour, salt, baking powder, soda, and sugar.
In another bowl, whisk together the eggs, milk, and melted butter. Combine with dry ingredients and stir until all ingredients are moistened. The batter should be thick but pourable, like a thick pancake batter.
Carefully, using pot holders, lift skillet out and turn to coat all of the inside surface with the melted shortening or bacon drippings. Pour in batter and return to oven. Bake for about 20 to 25 minutes, until browned.
