I make a similar style cornbread, but have made it simple:
1/2 box Jiffy Cornbread Mix
1/2 sack of Martha White Hush Puppy Mix
1/4 can of yellow cream style corm
1/4 c. sour cream
1/4 c. Jalapeno slices, chopped
Add buttermilk to get correct consistency-add grated cheddar cheese-pour into medium size hot iron skillet and bake at 400 degrees until golden brown.
