In a separate bowl, mix together all-purpose flour, cornstarch, cayenne pepper, paprika, garlic powder, and the rest of the spices. Dredge each fish fillet in the dry mixture, then dip them into the light beer batter, making sure it’s fully coated. Fry the fish for about 8 minutes, or until golden brown and crispy—oh, and don’t forget to drain them on paper towels after frying. They need to rest and absorb all that crispy magic!
