This is straight from the original book that came with my first Rival Crock Pot!
BAKED POTATOES
(... like foil-baked ... but no oven heat!)
Fill the CROCK-POT with scrubbed and well-greased potatoes. (It'll hold about 12!). Cover and cook on Low 8 to 10 hours. Do not add water.
(I'd poke holes in them, as mentioned above)
Merry Christmas!!!
