Step 1Whisk together the cornmeal, all-purpose flour, corn flour, salt, pepper, egg, oil and seltzer in a large bowl.
Step 2Insert a wooden skewer in each hot dog, then dust the hot dogs with flour. Roll or dip them in the batter so that they're totally coated.
Step 3Heat 1 inch of oil in a large wok or cast iron skillet to about 375 degrees. Cook a couple of corn dogs at a time until they are lightly browned, turning them over, about 4 to 5 minutes.Drain them on paper towels and repeat with the remaining hot dogs.
