Pickled Herrings or Mackerel
Have eight fresh herrings or four large mackerel cleaned and remove the heads. Lay not very[Pg 94] closely together with the backs upwards in a pie-dish. Fill the dish with vinegar and a few peppercorns, a little salt, an onion (sliced), and a piece of butter about the size of a walnut. Bake in a moderately quick oven for about one and a half hours. Serve in a glass dish and strain the vinegar over them.
