Sour Cherries

I think perhaps I was a bit misguided, or ill informed anyway, when I ordered 2 buckets of sour cherries at the local farm. I assumed that they'd be small buckets. Well, each is 10 pounds of cherries, already pitted. Did I mention that I've never made ANYTHING with a sour cherry? No time like the present, I guess. I plan to make some preserves, at least, and we'll see where else this goes. One step toward eating more locally...learn to use the ingredients available to you when in season!
