Unadulterated Black Bean Soup

1 lb Dried black beans

2 Ham hocks

1 md Red onion

1 md Yellow onion

8 c Water

1/2 t Salt

1/4 t Freshly ground pepper

1 tb Dry sherry or Madiera (opt)

Sour cream Chives This recipe is from Katherine Hall PAge`s "The Body in the Cast" (St Martin`s Press, 1993, $19.95). It`s from heroine Faith Fairchild`s cookbook, called "Have Faith in Your Kitchen." Faith notes that the soup tastes better if made a day ahead. Pick over beans, cover with cold water and bring to boil for 2 minutes. Remove from heat and let stand at least 1 hour. (Or soak beans overnight, changing water several times.) Drain beans and place in a large pot. Rinse the ham hocks. Peel and quarter the onions. Bury hocks and onions in the beans. Add 7-8 cups water and bring to a boil. Turn the heat down and simmer 1 1/2 to 2 hours. Be sure the beans are soft. Remove the hocks or bone and strip any meat from them. Add the meat to the soup and puree in batches in a blender. (Note: A food processor sometimes leaks with this much liquid.) Put the pureed soup in a clean pot; warm, adding the seasonings and wine, if using. Serve with a dollop of sour cream and finely minced chives.
