I love black grapes. There weren't available until Super Wal-mart moved in. Rural areas just don't get "fancy" ingredients like a black grape. We're kinda stuck with seeded grapes with very little variety. Anyway, in a search for recipes to use these beautiful little gems, I found this one, but there is one similar using green grapes here at Zaar. I find this one especially good. I make it a habit of tasting a grape from the bunch before I buy to make sure they're sweet.
