Wash fish and pat dry. Lightly season with salt and pepper and set aside. Combine seasoned salt and next 6 ingredients and mix well. Dip fillets in eggs, then in cornmeal mixture. Place fillets on a wax paper-covered plate and refrigerate at least 1 hour to allow cornmeal coating to set. In a large, heavy frying pan, preferably cast iron, heat bacon drippings and shortening to 370ºF. Oil is sufficiently hot when a haze forms above the oil and a drop of water can dance across the surface. Deep-fry fish until golden brown, drain on paper towels, and serve immediately. Excellent with slaw and Hush Puppy Patties. (4 to 5 servings)
