I brought this dish to a potluck and was asked for the recipe from a lady who now serves it in her catering business. This is easy to prepare and if you like the kick of a little vinegar, you'll like these beans.
Put all the beans with only a little of their juice plus the vinegar and brown sugar in a roasting pan and set aside. Chop up the ham (or bacon) in small pieces. Brown with the onion. Pour off any grease. Add onion and ham to beans. Bake at 350 degrees for 1 hour. (Or put in a crock pot for a few hours.)
