Here is a great family experiment that turned out fabulously!
I mixed sugar free jello with applesauce. I did about one quart of applesauce to one small box of jello, but really you can just do it to taste.
I then spread the mixture onto parchment paper as thin and uniform as I could get it right on my dehydrator racks. (I have a huge, old dehydrator that takes a while to get things done, but lets me do huge batches.)
I fit three quarts of applesauce in. We did three different flavors - raspberry, peach, and strawberry-banana.
Here is my big, behemoth! Without a thermostat, it doesn't do as well with evenly drying so I have to rotate the racks, but I can sure get a lot done. I had to leave these in all day and over night.
Here is my more common sized dehydrator with a thermostat. It probably would have dried a batch in about 6 hours so I could have completed just as much in the same amount of time I just would have had to refill it a few times - and worry about getting up after only 6 hours of sleep to turn it off. It also has round trays so the parchment paper would have had to be trimmed and it wouldn't do the long "fruit by the foot" I was imagining. I opted for the big behemoth.
When it was thoroughly dry and leathery, I cut it in long strips.
Rolled them up.
And packaged them all ready for school lunches. So easy, no sugar added, rolls of sweet goodness -
The kids have been loving them!
