Put a knuckle of veal into three quarts of cold water, with a small quantity of salt, and one small tablespoonful of uncooked rice. Boil slowly, hardly above simmering, four hours, when the liquor should be reduced to half the usual quantity; remove from the fire. Into the tureen put the yolk of one egg, and stir well into it a teacupful of cream, or, in hot weather, new milk; add a piece of butter the size of a hickory nut; on this strain the SOUP, boiling hot, stirring all the time. Just at the last, beat it well for a minute.
