Take any cold game or poultry that you have. You may mix several kinds together. Some sausages, of the best sort, will be an improvement. Chop all together, and mix with it bread crumbs, chopped onions and parsley, and the yolks of two or three hard-boiled eggs. Put it into a sauce-pan with a proportionate piece of butter rolled in flour. Moisten it with broth, gravy, or warm water, and let it stew gently for half an hour.
Cold veal or fresh pork may be hashed in the same manner.
