Mix the flour, cornmeal, salt, paprika, garlic powder, and black pepper in a shallow bowl.
This forms your dry coating mix that gives the fish its crispy finish.
In another bowl, whisk the egg and milk together.
This acts as the wet coating to help the dry mix stick to the fish fillets.
Dip each fish fillet into the egg mixture, ensuring it is fully covered.
Then, coat the fish in the dry flour mixture, pressing lightly to adhere.
Heat the oil in a large skillet over medium-high heat.
The oil should be hot enough to sizzle when a drop of water is added!
Carefully place the coated fish fillets in the oil and fry for about 4-5 minutes on each side.
Cook until they are golden brown and cooked through.
