I've really "gotten into" this dehydrating thing. Food keeps longer than in the freezer, it's faster and cheaper than canning (plus you don't lose all your vitamins and such) and it really saves space.. So far I've dehydrated onions, zucchini slices (with assorted spices), peppers, sliced potatoes, cinnamon apples, bananas, yogurt, and TOMATO JUICE!
Now, THAT was a trick. And a mess. And I need to find a better way.
Here's a visual. Put parchment paper on a flat tray without sides. Pour a puddle of tomato juice in the center. Balance the tray, without slopping the tomato juice, and slide it into the dehydrator. Repeat.
I did probably a peck of tomatoes by just dipping them in boiling water to remove the skins, whooshing them in the blender to make juice (seeds and all....gotta love that VitaMix!), and then drying the juice. That peck of tomatoes made about a half-quart of tomato paste powder. It dried into crispy sheets of tomato leather, and I just crumbled them into a jar. Of course, I had to sample a piece or two. <grin>
By the way, the dehydrated yogurt is pretty good stuff!!! I just dumped a container of fruited yogurt on a tray and dried it. Then broke it into pieces. It tasted like fruity taffy. Ummm!
