Rinse the trout under cold running water. Pat dry. Sprinkle with salt and pepper. Melt the butter in a large heavy skillet on medium-high heat. Coat the trout in corn meal and shake off the excess. When the butter is melted, place the coated trout, flesh side down, in the skillet. Fry 4-5 minutes, then turn and fry 4-5 minutes or until the flesh is golden brown and flaky. (Trout may be seasoned with garlic or onion powder before frying, if desired.)
