Wash and wipe the fish, and lay it, heads and tails, in a baking-dish,
the bottom of which has been spread all over with a little butter or
dripping, add a little vinegar and water, and, when procurable, some
mushroom ketchup. Season with chopped onions and parsley, shake plenty
of raspings of bread all over the top of the fish, and bake it in your
oven, or send it to the baker's.
