Pears! Like candy! I also dehydrate potatoes as shreds for hash browns (a quick plunge in boiling water keeps them from discoloring)- to make hash browns you just soak them 1:1 in hot water for about 10 minutes, then throw them in the skillet. I prefer them as they don't break up and go mushy as easily as fresh potatoes do. I also dry onions, peppers, tomatoes, and all kinds of fruit. I found that plums get MORE sour rather than less when they are dried (at least mine did) but hubby likes them that way.
I like dehydrating eggs when my ducks give me more than I can handle in early summer, for use in winter when they don't do as well. I got some of the solid sheets that are used for fruit leather (they are round and my dehydrator is rectangular, but it's all good). I whisk fresh eggs until thoroughly mixed then pour them into the sheets. Each round sheet holds about 4 duck eggs for me. Then I dry them on the highest setting. They usually take about 10 hours. Then I whirl the eggs in a blender to turn them into a coarse powder. Two tablespoons of powder mixed with 2-2/3 Tablespoons water equals about 1 egg. I use them for baking to make sure that any bacteria that might have proliferated while the eggs were drying will be thoroughly killed in the baking process. (PS: this is NOT a tested and approved recipe. I haven't had any problems doing this, but be aware there are risks when holding raw egg at dehydrator- temperatures for hours at a time)
