I've also got more blueberries, and I tried my hand at drying them too. DISASTER!!!!! I had read somewhere that you had to blanch them before drying to remove a natural wax and to open cracks in the skin. So I blanched them, but left them in the hot water too long, so they got all gloppy and stuck together. I tried to dry them anyway. It did not work. Short story is, I had to throw away about three pounds of blueberries. :( And on top of that, I reread the book, and it was the grapes that had to be blanched, not blueberries. How I got that confused, I don't know. So I'll have to try again.
I also need to get out and start picking the blackberries. In fact, I'm going to go out and do that right after I finish this post. I'm thinking apple-blackberry butter, blackberry syrup, and blackberry jelly.
