Brown Sugar Ham and Bean Soup

1 lb navy beans, soaked overnight
1 meaty ham bone
1 small onion, chopped finely
1 cup cream
1/2 tsp dry mustard
1/8 tsp ginger powder
1 cup brown sugar

Place navy beans and ham bone in crock pot and fill with enough water to cover beans and most of ham bone. Cook on low for 3-4 hours. Add remaining ingredients and cook an additional 2-4 hours. Take bone out and shred remaining meat off bone and add to soup. Serve with a crusty loaf of bread and a salad. Delicious.
