I'm glad to report that the fruit roll ups were a big success! We've almost eaten all of them since we've been home. They are very sweet like the store bought kind, but are made with only fruit and yogurt. I'm going to have to invest in more fruit roll up sheets!
I also decided to put some grapefruit on the dehydrator just to see what happened. They are excellent! They have a really sour burst at first, but then get really sweet. I like grapefruits anyway, but KB is not a huge raw grapefruit fan and he really liked the dried ones.
Pretty soon I'm going to be as bad as the crazy midwestern lady that I made fun of when I first started drying fruit!
