Do you own one? What do you do with it?
My favorite thing to do is dehydrate pieces of fruit like sour apples with cinnamon and a bit of maple syrup dropped on top.
Works very well with wild gourmet mushrooms found in the field, and I would imagine this can also apply to drying psychoactive ones (on a low heat setting.)
These things are also good for drying fresh herbs like basil and parsely when you know you won't use them for awhile.
In my experience, bananas do not turn out to tasty, so I would recommend sticking to sweet or sour fruit.
Something tells me no one here has one of these or cares, but I thought I'd throw it out there.
New ideas couldn't hurt.
