This is GF, but not CF.
I used the Maseca brand corn flour for tamales.

2 cups of Maseca
2 cups lukewarm broth or water
1 teaspoon baking powder
1/2 teaspoon salt
2/3 cup lard or vegetable shortening. I used margarine instead.

Combine the dry ingredients with the liquid in a bowl.
In a separate bowl, beat shortening until fluffy, add masa dough and beat until dough has a spongy texture.

Using a spoon or your fingers, scoop up masa and spread over a hot dog with your fingers. Coat each dog with masa dough. Once they are covered, you should be able to lightly roll each between your palms to smooth out the covering.

Fry on all sides in a lightly oiled pan. You could also deep fry, but I opted for a lightly oiled cast iron fry pan in order to cut down on the greasiness. After all, there's already a ton of grease in the dough itself. I also tried steaming some of the corn dogs, like tamales would be steamed, but was not pleased with the result. They need that crunch frying gives them.
Enjoy!
