1. Scrub the potatoes super, squeaky clean and dry them completely.
2. Prick each potato a couple of times with a fork.
3.Wrap each potato tightly in the foil, place in the slow cooker and turn on low.
4. Take two paper towels (don’t rip them apart from each other) and lay them across the top of the slow cooker, but not down into it. Place the lid on top. That will keep the moisture that builds up from dripping down onto the potatoes.
5. Cook on low for 10 hours or on high for 4-6 hours.
