I must be in a minority, but other than convenience I don't think much of the Jiffy mix.
The end result is too sweet, to begin with (down hear we sometimes do mix sugar and meal. But we call the result "cake."). And I don't like the texture; it's crumbly without having a decent crumb. And, at base, I don't find that there's much flavor to it.
Plus, of course, for those for whom it matters, Jiffy contains lard in one of three forms.
Fact is, there are dozens of cornbread/muffin/sticks recipes out there, none of which involve particularly more work than the Jiffy. And not all that much time difference either.
Among several that I have, my day-in, day-out favorite came from a small, family diner in Cumberland, Kentucky---a little town nestled in the hill country. This was the recipe used by the owner's grandmother, and she graciously shared it with me:
Leonda's Cornbread
1 1/4 cups each self-rising cornmeal and self-rising flour
1 1/4 cups buttermilk
1 1/4 cups water
Pinch salt
Oil
Mix dry ingredients. Mix buttermilk and water, and gradually add to flour mix to form a thick batter.
Spray a 10" (cast iron) skillet with cooking spray and add enough oil to form a layer about 1/4 inch thick. Put skillet in oven, and preheat to 400F.
Remove hot skillet from stove. Pour in batter. Return to stove and back for one hour. If the bottom seems to be browning too quickly, flip the bread the last 15 minutes or so.
My buddy Dave Reed came up with this recipe specifically for corn sticks:
Dave's Corn Dodgers
2 cups cornmeal
1 cup whole grain flour
2 eggs
1/2 cup honey
1 cup milk
1 tbls baking powder
Mix ingredients together. Bake in preheated, oiled cornstick mold for 10 minutes at 450F.
There are two kinds of cornstick molds; those that make cylindrical sticks (sort of like Slim Jims) and those that make corn "ears." I have both kinds. The straight stick ones are, historically, more original. But, frankly, the "ears" are more fun. And the molds for them more readily available, too.
