We did a fish fry for my father-in-laws 80th birthday. He'd caught all of the walleye and bluegills that we cooked, so we figured it was the least we could do for him.
No real recipe was needed for this meal. We had numerous fish filets of varying sizes. We did two different "breadings". One was the traditional egg wash/flour. Just beat some eggs to incorporate the yolks and the whites. Take the filet and dip into the wash, then take it out and place it into a pan of flour. I mixed into the flour some Lowery's Seasoning Salt and some Lemon Butter Pepper. Dredge the filet with flour, shake off the excess flour and place into the oil, which should be at least 350 degrees. The second "breading" was cornmeal. Just dredge a filet in the cornmeal, which had nothing added to it, shake off the excess and drop into the oil.
I used 2 dutch ovens to do the cooking. A 10" regular, which I cooked the cornmeal filets in, and a 12" regular, which I cooked the egg wash/flour.
I did "cheat" and use my gas grill instead of coals. I did this because it would be easier to maintain a constant oil temperature while doing all of the cooking at the same time. We were going to be feeding about 18 people, so we had a lot of deep frying to do in a short time, so I wanted to make it as easy as I could.
Everything worked out great, and the fish was delicious. Hope you all try doing this sometime if you haven't already.
