Onion Soup

Mix one or two tablespoonfuls of oatmeal in cold water until it is quite smooth,
then pour in gradually three pints of liquor in which a leg of mutton has been boiled,
turn all into a stewpan with several peeled and chopped onions, and cook until of the
consistency of cream, or leave out the oatmeal, substitute wheat flour, and stir it into
the soup while boiling; a few minutes before serving add the yolks of two or three
eggs, removing the pan from the fire before putting them in.
