Dress, scale, and what the fish, pat dry, salt and pepper, then dredge them in the meal or meal-flour combination.
Heat the fat until it is hot enough to cook at once, but not burning, sputtering hot. Lay in the fish, turn heat down to barely a medium flame, and begin to brown the fish. Keep the fish loose from the pan bottom with a thin metal spatula.
Taking 8-10 minutes to a side (turn heat low if it seems to fry too fast), brown the fish slowly until crisp. Do not overcook. When the flesh is opaque the fish is done; one hopes it's all browned by then.
Add 4 Tbs. butter to the skillet after removing the fish and squeeze in the juice of a lemon, stir the fat and juices to loosen the dredgings, and pour over the browned fish.
