Step 1

Season fillets with salt and pepper. Dust with 1/3 cup of flour.

Step 2

Beat buttermilk and egg in a bowl. Combine remaining flour, cornmeal, seafood seasoning, baking powder, and baking soda in another bowl. Dip all flour-dusted fillets into egg mixture, then into seasoned flour mixture.

Step 3

Heat oil over medium-high heat in a large frying pan or deep fryer. Fry fillets, working in batches if needed, until golden, about 2 minutes on each side. Season again with salt as soon as your take them out of the pan or fryer.
