I have instructions that call for steaming them first and then putting the slices on the dehydrator.
However, I had bought a plastic kit to make micro wave potato chips a few months ago. It included a mandolin that slices the potatoes paper thin, and the plate to cook them on.
So Hubby experimented and used that mandolin and then put the slices on the dehydrator, and it worked. I was skeptical and thought they would probably be discolored, but they weren’t.
So that’s how we do it. Lots less effort.
My favorite so far with the dehydrator was my tomatoes. They took a long time but I blended them into a powder once they were good and try. They take up very little space this way and a couple of tablespoons really add a wonderful flavor to soups/stews. I don't have any of the mats yet so haven't tried the fruit leather or anything like that.
Has anyone tried to dehydrate scrambled eggs? We have plenty of eggs from the chickens and thought I might give it a whirl soon.
