I got this recipe from “Not Your Mothers Slow Cooker Cookbook.” and have wanted to make it for awhile. If you google Senate Bean Soup you will get a zillion hits
1 large ham hock
10 cups of water (I find this will vary according to the size of your pot)
2 medium size yellow onions minced
3 medium sized baking potatoes peeled and cubed
6 ribs of celery including ribs finely chopped
1/3 cup chopped flat leaf parsley
1/4 tsp of freshly cracked black pepper or to taste
salt to taste
2 Drain taking care not to splash yourself with hot water. Add onions, potatoes, celery and half the parsley, the beans and ham hock. Add the ten cups of water. (I have a 7 quart crockpot and 10 cups was too much water) Cook on low 8-10 hours. (I cooked on high for that long because the pot was so full.
3 Add the rest of the parsley, salt to taste and more pepper. Cook for 15 minutes more.
4) Remove ham hock, let cool and take meat off and put it in the soup. (I sliced up some polish sausage and added them to pot to heat through)
I did some research on this soup and found this from the United States Senate
