Young ducks are essential for this purpose. Lay three slices of fat corned ham upon the grating of your roaster, and upon them a minced onion, a stalk of celery, chopped, a sliced carrot and a tablespoonful of chopped parsley. Clean and truss, but do not stuff the ducks; lay them upon the prepared "bed," and pour a cupful of boiling water over them. Cover the pan and let them cook, closely covered, in a moderate oven for about two hours. Take up the ducks, strain the liquor from the pan, and let it cool enough to remove all the fat. Then put it into a saucepan, and let it boil. Add one teaspoonful of lemon juice, and thicken it slightly with browned flour. Return the fowls to the sauce till hot again, then serve with the sauce poured over them.
Melt in a saucepan two tablespoonfuls of butter, and stir into this a half tablespoonful, each, of chopped ham, onion, celery, sweet pepper and parsley, with a tablespoonful of flour, a quarter of a teaspoonful of salt, and a half teaspoonful of paprika. Stir for three minutes, then add a cupful of consomme, two cloves and a blade of mace. Simmer for an hour; strain and add to it two cupfuls of cold duck, cut into neat pieces an inch long. Boil one minute to heat the meat thoroughly, and serve.
