Some popular ways to deep fry fish are pan frying or by using a deep-fat fryer. To pan fry a fish, begin by coating the fillet with a mixture of egg and cornmeal or bread crumbs.
There are many different recipes for the coating mixture. For example, the mixture that is used in the crispy fried fish recipe on Allrecipes.com is made by first combining 1 egg, 1 1/2 cups of beer, 1 cup of all-purpose flour, 1 teaspoon of garlic powder, 1/2 teaspoon of salt and 1/2 teaspoon ground black pepper in a large bowl. In a separate bowl, mix together 2 cups of crushed cornflake crumbs and 1 teaspoon of Cajun seasoning. Dip the fish fillets into the egg-and-beef mixture, and then coat them in the cornflakes and Cajun seasonings.
To pan fry the fillets, fill a large skillet 1/4 of the way with vegetable oil. Wait until the temperature of the oil reaches 365 degrees Fahrenheit. Place each fish fillet into the skillet. Cook each side of the fillet for three to four minutes, or until it is golden brown. Drain each fillet on paper towels.
To use a deep-fat fryer, begin by pouring 2 inches of vegetable oil into the fryer. Cover the fish with flour and a batter that is made out of 1/2 cup of all-purpose flour, 1/2 cup of beer, 1 egg and 1/4 teaspoon each of baking powder, salt and ground black pepper. Fry the fish for three to four minutes.
