I had one years ago, I did a number of things, what turned out best that I actually used, was apples and pineapple. Both of those very nummy. One thing I did that turned out to be a mistake, was I did a big batch of onions in the house! My eyes watered for a couple of hours, then I thought the smell went away. Well, when I went to work, co-workers wanted to know where the onion smell was coming from. It was in my skin, my hair, my clothes, everywhere. It took a few days to go away. I would not recommend drying onions in the house with a dehydrator!
