What kind of psychopath just throws food in the fridge without covering it first? Do you want it to dry out and taste like the lining on the refrigerator walls?
If done in a controlled environment, it's apparently very tasty! I recently stumbled upon a tutorial somebody made recently about how to make watermelon jerky with a dehydrator. Apparently the flavor gets significantly sweeter. He was making it for hiking/survival purposes, so removing all the water weight lets you pack a lot of lightweight nutrients, too.
