I'm not sure what made me want to make my own raisins other than just having a lot of (free) grapes and a food dryer.
Wash, pull from stems and fill dehydrator.
No joke about the time it took- I think our food drier must not be that amazing or something. It is something we inherited from my husband's grandma. And it wasn't truly 2 days. I did turn it off now and then when someone was here or I was going to bed. I doubt I will make them again, but it was kind of fun - at least the idea of it.
