I was cleaning up some old packaging (as well as taking down the Christmas tree) when I noticed that this box full of packing peanuts had a note in it that the peanuts were made of cornstarch. Intrigued, I got one wet and it melted away. So I dumped the whole box in the sink and stirred it in hot water until they dissolved. They washed right away. I wonder if I could thicken a sauce with them, too?
