Good, relatively simple summer dessert for crab feast?

Grape salad! The totally controversial entry from the NY Times for regional Thanksgiving specialties! The Internet exploded when the NY Times claimed that grape salad – Thompson grapes, sour cream and brown sugar – was a traditional Thanksgiving dish in Minnesota. Midwesterners of all stripes claimed an anti-midwestern bias by the NY Times. Recast as a modification of a chic French picnic good, it has much more cache!

PS Seriously! Google grape salad!
