After having carefully cleaned, salt well and lay it in the baking-pan
with a small cup of water, and strew flakes of butter on top, also salt,
pepper and a little chopped parsley. Bake about one hour, basting often
until brown. Serve on a heated platter; garnish with parsley and lemon
and make a sauce by adding a glass of sherry, a little catsup and
thicken with a teaspoon of flour, adding this to fish gravy. Serve
potatoes with fish, boiled in the usual way, making a sauce of two
tablespoons of butter. Add a bunch of parsley chopped very fine, salt
and pepper to taste, a small cup of sweet cream thickened with a
tablespoon of flour. Pour over potatoes.
