Mackerel Broiled, and Tarragon Butter Recipe ingredients

To prepare this Mackerel Broiled, and Tarragon Butter Recipe, first remove the inside of the fish through the gills and vent without opening it. Wash, clean, dry, and make a deep incision down the back; lay the fish in a little salad-oil; keep it well basted for about three-quarters of an hour, but cut off the nose or part of the head and tail before it is steeped in the oil. Broil over a clear fire, and when done, have ready the following mixture, with which fill up the incision: Work a little butter, pepper, salt, and tarragon-leaves chopped and steeped in vinegar together. When ready, serve the mackerel with some of the butter spread over it on a hot dish. Time, from ten to fifteen minutes to broil.
