Scrub baking potatoes and dry thoroughly. Pierce each potato with a fork, about 3 times on each side.
Cut a square of foil, large enough to accommodate wrapping up potato. Put about 1 tsp of mixed up salt in the center. Place potato on top of the salt. Wrap up in foil, shake the potato to distribute the salt.
Place potatoes in crock pot, standing up. Cook on low 8 hours. Serve with toppings of choice
TIP: You can cook as many potatoes as you want, just don't stack them, they will not cook. For best results, stand potatoes up.
