I have a hard Tim using up potatoes before they go bad. I would like to try to dehydrate some sliced potatoes.
Does anyone know how or if this can be done? I have a food dehydrator. I am thinking the potatoes should either be blanched or all the way cooked before dehydrating. Help will be appreciated.

Yes, you can dehydrate potatoes. Yes, you want to blanch them -- otherwise they may turn black. According to the So Easy to Preserve book published by the University of Georgia Cooperative Extension, you should "wash, peel, and cut into shoestring strips 1/4 inch thick, or cut into slices 1/8 inch thick", then steam blanch 6 to 8 minutes, or water blanch 5 to 6 minutes. Estimated dehydrator time: 7 to 12 hours. FWIW: I'm in the process of getting certified as a Master Food Preserver, and this is our text book. Just finished dehydration today. :)
Here's one of my favorite books of food home systems. http://www.amazon.com/Home-Food-Systems-Processing-Preserving/dp/0878573208
Rodale's Home Food systems. It's a catalog, encyclopedia...with tons and tons of information. Too much really. It doesn't get too specific on any specific items but focuses on basic tech and hardware. Including things like DYI stuff and even things like turning a back yard pool into a fish farm. Bees, raising goats, making cheeses, canning, juicing, etc..etc. Something to look up if you can find it--it's out of print now, I think. But it's wonderful read...filled with all types of info and suggestions for hardware--much of which are still available today.
