   1      pound         beans - black -- turtle, pink, or
                        -- pinto
                        an earthenware bean pot -- (I, used my crock
                        -- pot)
  10      cups          hot water
     1/4  cup           white onion -- roughly sliced
   2      tablespoons   lard
   1      tablespoon    salt -- or to taste
   2      large   spri  epazote -- (only if, black
                        -- beans are used

Preparation:

*Pinto or pink beans will need 12 to 14 cups water Rinse the beans and run them through your hands to make sure that there are no small stones or bits of earth among them. Put the beans into the pot and cover them with the hot water. Add the onion and lard and bring to a boil. As soon as the beans come to a boil, lower the flame and let them barely simmer, covered, for about 3 hours for black beans and 2-1/2 hours for the other varieties, or until they are tender, but not soft. Do not stir during this time. Add the salt and epazote, if you are using it, and simmer for another 30 minutes. Set aside, preferably until the next day. There should be plenty of soupy liquid.
