Long John Silver's Deep Fried Fish

2 pounds cod sliced into 3 ounce pieces (you can use other types of fish)
2 cups flour
1/4 cup corn starch
2 teaspoons sugar
2 teaspoons salt
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon onion salt
1/2 teaspoon paprika
1/4 teaspoon ground black pepper
16 ounces club soda
Oil for frying

If you are not using a fryer, heat up 8 cups of vegetable oil in a heavy pot until the temperature reaches 350 degrees. Make the batter by combining flour, corn starch, sugar, salt, baking powder, baking soda, onion salt, paprika, ground black pepper. Stir to combine all dry ingredients. Add club soda to dry ingredients. The batter will foam, continue to stir.

Drop pieces of fish into the batter. Coat fish with batter, drop into hot oil. Fry fish for 2 to 3 minutes or until the batter is golden and the fish pieces begin to float to the top of the oil. Drain fish on a wire rack.
