Whenever I purchase a ham for a family meal, I prefer to buy it with a bone. This way, I'm sure to have the bone and some extra ham to put in the freezer for another meal. For this recipe, I used a ham bone with a pound of meat still attached to the bone. I defrosted it in the microwave and added it directly to the slow-cooker. The ham bone gives this soup such great flavor. And if you buy a ham that has been smoked, that wonderful smoky flavor gets added to your soup as well.
