This is a recipe I came up with when I had an excess of potatoes. These are sooooooo much cheaper than buying premade mixes. It takes a bit of effort, but it's worth it! Something I also like is the fact that it doesn't have the sulfites that some products include. I don't bother peeling the potatoes before I make these, but then again I don't normally ever peel potatoes...I cook them with the skins on. You could do either. I used a corkscrew slicer (looks like a screw with a piece of metal attached) because that's what I had. It created a hole in the middle, which I wasn't sure I liked, but it probably helped the potatoes dry faster in the long run. If you use the corkscrew slicer, the potatoes will come out looking kind of like a big slinky. Set the potato on it's end and cut through all the slices...it will separate them into individual slices. If desired, you could use a mandoline, but I think I like the corkscrew slicer better due to decreased drying time. Drying time not included in recipe, as it will vary from model to model.
