Preheat oven to 450 degrees F. Dip Danah crème dori fillets into melted butter and place on a non-stick broiler pan. Sprinkle fish evenly with lemon pepper and cayenne pepper. Place onion rings on the fillets and then sprinkle with Worcestershire sauce. Bake for 8 minutes on the centre oven rack, then turn on broiler at 500 degrees, and allow enough time to brown the fish and onions (3-6 minutes). Remove and allow the fish to cool for 3 minutes. Squeeze lemon over the fish, and serve hot. Yield: 4 servings.
