This is a nice recipe for cornbread. It's a modification of the 1979 Fannie Farmer Cookbook recipe.

In a big bowl, mix the cornmeal, flour, sugar, baking powder, and salt. Beat the egg, melt the butter, and add the egg, butter, and milk to the mixture. Mix well. Optionally, add some fried onions, jalapeño peppers, and cooked breakfast sausage. Pour the mix into a hot buttered 6" or 8" cast iron frying pan, and bake at 425°F (220°C) for 20 minutes. Let cool and eat.

Masa (corn flour) can be used instead of cornmeal. Simply substitute in equal parts. This changes the texture, and the bread might rise more than with cornmeal, but the taste is quite nice.
