Cambridge International Dictionary of English: Raisin - noun - a dried black grape.
Okay, so these aren't black grapes. Do they still count? As far as I can tell, they are actually "Sultanas."
This is about half way through the process. You can see that they are starting to shrivel nicely. I've never actually made raisins before...it's always been dried cherries (very yummy), occasionally blueberries, and, of course, fruit leather. I really have no idea how long this is going to take, so I'm just winging it. So far, it's been about a day.
