Wow, my dehydrator must be old. There's no temp control on it - it just turns on and off.
I've come across a lot of "raw foods" recipes for bars/cookies that are put in a dehydrator, but don't have any recipes of my own to share.
I always just used it to dehydrate veggies in season (or that I got on sale), and then put them in soups and things through the winter months when they were less abundant. I even chopped meat (like turkey or chicken) and dehydrated that. At the time we lived in an earthquake zone, and preparing for times when you had no refrigeration was prevalent.
I haven't used mine again until recently, when I dehydrated some orange peel to grind up and have to add to teas, cookies and whatever.
