I fry all my fish in a cornmeal/flour mixture 3:1 ratio. I soak fillets in buttermilk for a few minutes and then dredge them in the cornmeal/flour mixture. Set aside for 20-30 minutes and the batter will stick to the fish much better. 360-375 degrees in peanut or canola oil with prevent them from being greasy. Season with your favorite seasoning just when it comes out of the pan or deep fryer.
