There are more ways to bake corn bread than ants at a dinner on the ground. My mom made her's one way and the old black woman who worked for us did it a different way, both great and just right under a big bowl of greens.
The thing about self rising corn meal and corn meal mix is they both have baking powder and baking soda to insure a good rise with or without butter milk.
For convenience I use a mix now, leave out the sugar and flour. Pour it into a hot cast iron skillet or dutch oven with hot oil heated in the skillet while the oven is preheating.

A lot of times I will make cornbread pancakes. These can be made like corn bread or simply with meal and salt and hot water. No one has ever complained and it is usually gone after dinner.
