Years ago, during a particularly hot summer spell, a friend told me about her favorite hot weather snack. She would clean a bunch of seedless grapes, put them in Ziploc bags, and freeze them. I was a bit skeptical, but gave it a try. Wow! I was instantly hooked on frozen grapes. They’re a bit sweet (depending on the variety), cold, and juicy. And best of all, they’re a healthier snack than an ice cream bar.
