Take half the salmon and lay it open without quite dividing; take off the skin with a sharp knife, moisten the fish with a little olive oil, pepper and salt, and let lie in the pan an hour or two. An hour before dinner make some fresh roast meat fat hot in the pan and bake brown in about half an hour, basting once or twice with clear butter. Drain away the grease, or move the fish into a clean pan. Serve small portions cut with a fish slice with tartar sauce at the side and potatoes in some special form on the same plate.
