1 ) Add the potatoes, onion, carrot, celery, ham, Kosher salt, pepper chicken broth to your slow cooker and cook on low 7-8 hours, or high 4-5 hours.
2 ) Using a potato masher, mash about 1/3 of the potatoes (don’t worry the ham won’t really mash that much)
3 ) Add the flour, heavy cream/milk and sour cream and stir everything together.
Cover and cook on high for an additional 15 minutes.
