You can fry any fish this way. Our favorites in particular are catfish, swai and speckled trout. I saw this concept on one of the cooking shows but cannot remember which one. This also would work with fried chicken or pork chops.
1Wash fish fillets and set aside. My pic is swai this time. We also love catfish and speckled trout this way.
2Mix together buttermilk and half that amount of sour cream. For instance if you are using 1 cup buttermilk then use 1/2 cup sour cream. This amount depends on how many fish fillets you are using so use your own judgement. Mix in salt, pepper and paprika and whisk until well combined.
3Place fish fillets in a bowl with lid or ziplock bag and pour in the buttermilk mixture and refrigerate for at least one hour or up to several hours, turning the bag (or bowl) occasionally.
4To fry: Put two plastic grocery bags together and put in the flour, salt, pepper and paprika. Combine together by gently moving the bag back and forth. Again use your judgement as far as the amount, which depends on how many filets you're frying. Add in the fish fillets. Securely close up bag by twisting top then gently shake the bag until fillets are well coated.
5Take out fillets and shake off excess flour and place onto a cookie sheet. Get out skillet and heat up the oil or shortening you'll be frying them in.
6Place in hot oil or shortening and fry to a golden brown or to your likeness. Be careful not to over cook.
7Serve with tartar sauce, lemon wedges, vinegar or just plain. As sides we enjoy boiled or baked potatoes, slaw and hushpuppies.
