First, wash your potatoes. Once washed, you may peel the potatoes, but generally, I just leave the skins on. More nutritious this way and it eliminates a step if you do not peel them. Now, get your mandolin out. Just slice your potatoes. I use the "medium slice".
Once they have boiled for 3 minutes, drain them and run cool water over the potatoes to stop the cooking process. Then just lay the potatoes out onto your dehydrator trays and dehydrate. I turn on my dehydrator on before I go to bed and the potatoes are done the next morning. Place in a clean mason jar with a lid and store in a cool, dry area.
These actually are peeled but like I said previously, generally, I don't even bother to peel them. To reconstitute, just take the desired amount of potatoes and place in a pot or bowl and add enough of really hot water to cover the potatoes. Let set 10 minutes and they are ready to use.
