BLACK BEAN SOUP.
Soak a pint of black beans in two quarts of cold water over night; boil them four hours or more; mash them thoroughly, strain them through a colander into a saucepan, cover, and let boil. Mix a tablespoonful of flour smoothly with cold milk or cream, stir into the boiling soup until it thickens; add a cupful of butter; if it is too thick, thin with boiling water; add a tablespoonful of lemon juice. Season and spice to taste.
