Veal or chicken must be used for this soup; and the stock must always be prepared the day beforehand, having been flavored with two chopped onions and a cup of cut celery, or celery-seed and other seasoning, in the proportions already given. On the day it is to be used, heat a quart of milk; stir one tablespoonful of butter to a cream; add a heaping tablespoonful of flour or corn-starch, a saltspoonful of mace, and the same amount of white pepper. Stir into the boiling milk, and add to the soup. Let all boil a moment, and then pour into the tureen. Three eggs, beaten very light and stirred into the hot milk without boiling, make a still richer soup. The bones of cold roast chicken or turkey may be used in this way; and the broth of any meat, if perfectly clear, can serve as foundation, though veal or chicken is most delicate.
