Prepare the Pecan Crab Relish, and set aside. Prepare the Lemon Butter Sauce, and keep warm.
Preheat the oven to 375degrees F.
Sprinkle 3/4 teaspoon Creole Seasoning over each fish steak or fillet, and pat it on with your hands.
In a bowl combine the 1 cup of the flour with 1 tablespoon Creole Seasoning. In another bowl combine the pecans with the remaining 1 cup flour and the remaining 1 tablespoon Creole Seasoning. In a third bowl beat the eggs together with the milk.
Dredge the seasoned fillets first in the seasoned flour, then in the egg wash, and finally in the pecan/flour mixture. Gently shake off the excess.
Heat the oil in a large ovenproof skillet over high heat. When the oil is hot and almost smoking (about 375degrees F), add the fish and saute until golden, for about 1 1/2 to 2 minutes on each side. Turn the fish back to the first side and place the skillet in the over until the fish is brown and crisp, for about 4 minutes.
To serve, pour about 1/3 cup of the Lemon Butter Sauce on each of 4 dinner plates, place a fillet on the sauce, and top with 1/2 cup of the Pecan Crab Relish.
