Wash and dry catfish fillets. Sprinkle both sides of fish with garlic powder, salt, pepper, paprika and a pinch of tarragon. Place "what would be skin side" down in a greased 9x13 inch pan.
Mix together juice of lemon, sherry and soy sauce. Pour over fish. Dot each fillet with butter. Bake at 350 degrees uncovered for 30-45 minutes, depending on size of fillets. Baste fish once as juice thickens. Remove from oven with a little thickened juice remaining to baste fish. Or, can cook until juice evaporated. Either way is good.
