Thoroughly clean the fish; cut off the head or not, as preferred; cut out the backbone from the head to within two inches of the tail, and stuff with the following: Soak stale bread in water, squeeze dry; cut in pieces a large onion, fry in butter, chop fine; add the bread, two ounces of butter, salt, pepper and a little parsley or sage; heat through, and when taken off the fire, add the yolks of two well-beaten eggs; stuff the fish rather full, sew up with fine twine, and wrap with several coils of white tape. Rub the fish over slightly with butter; just cover the bottom of a baking pan with hot water, and place the fish in it, standing back upward, and bent in the form of an S. Serve with the following dressing: Reduce the yolks of two hard-boiled eggs to a smooth paste with two tablespoonfuls good salad oil; stir in half a teaspoon English mustard, and add pepper and vinegar to taste.
