POTTED MACKEREL

Pound together an ounce of black pepper and six blades of mace. Mix with two ounces of salt and half an ounce of grated nutmeg. Rub thoroughly into pieces of fresh mackerel, and fry in oil. Drain, and put the fish in a stone jar. Fill with vinegar, and put two tablespoonfuls of oil on top. Cover closely and let stand for two days before using.
