We just got a food dehydrator. Our house has been operating at a low hum for the past 48 hours and we've been enjoying fruit roll-ups (strawberry-banana, apple-grape, and my personal favorite -- cherry) and dried pineapple. Next to come are dehydrated full meals, like chili and pasta.
Jason is about to embark on a long hiking and camping trip along The Long Trail through Vermont. He's decided to take along a lot of dehydrated food so that he'll have variety throughout the month he's gone. It'll surely be an interesting experiment.
