Take 2 lbs. of razor-fish, and, after they have been well washed, put them into a saucepan, and keep them on a slow fire till they open, then take out the fish from the shells. Chop up some parsley very fine, and put it, with a tablespoonful of oil or an ounce of butter, into a saucepan, and fry until it becomes brown. To this add a pint of water, or a pint and a half of milk, and, when boiling, place in your fish, with a little salt and pepper, and let it boil again for half an hour.
