Pat the fish fillets dry with paper towels.

In a large mixing bowl, whisk together the flour, cornmeal, baking powder, salt, and paprika.

Gradually add the cold water (or beer) while whisking until a smooth, thick batter forms.

Heat about 2 inches of oil in a frying pan or deep fryer over medium-high heat.

Dip each fish fillet into the batter, allowing excess to drip off.

Carefully place the battered fish in the hot oil and fry for about 4-5 minutes on each side until golden brown.

Remove the fish using a slotted spoon and drain on paper towels.

Serve the fish hot with your favorite sides.
