I have used this recipe for thirty years. It is from a 1974 cookbook called "Country Cooking". It was one of Southern Living Magazines books. I have been using oil in place of the butter that was called for in the original recipe for years with good results. The secret to this cornbread is a "screamin' hot" iron skillet, greased only on the bottom, and a hot oven. I serve this with chili, vegetable soups, and tex mex.
