Slice 2 of the onions and put half in bottom of a crock pot. Add meat, cloves
and water with remaining sliced onions on top. Cover and cook overnight for
8 to 12 hours on LOW.
After cooking pork, remove bone and fat from meat. Put meat back into crock
pot. Chop remaining onion and add with barbecue sauce. Cover and cook additional
1 to 2 hours on HIGH or 4 to 5 hours on LOW, stirring two or three times.
Serve on buns.
With about 5 servings per meal, you'll have extra to freeze for another day.
