Boing Boing has a great link to a guide to making summer sorbet in an interesting (and pretty easy looking) way. From the site
today i'm making my special sorbet in a sack. armed with just a couple of plastic bags and some rock salt i will transform this fruit juice into a refreshing sorbet in just minutes. its the perfect snack after a busy day of play, work or adventuring!
It must be seen to fully enjoyed though, as it's being prepared by a stuffed animal. Unfortunately for some folks, it's a Monkey.
