Glazed or candied grapes
Long ago in a restaurant in Manhattan called Le Perigord Park (now closed) at the end of the meal they served candied grapes with coffee. They basically tasted like grapes with a hard sugar coating, sort of like a candied apple shell only thinner.
Any suggestions on how to replicate that taste?
maybe you could boil sugar to hard crack stage and dunk the grapes into it and maybe perhaps into iced water to stop the cooking?
Here's a recipe for Frosted Grapes, sounds like it may be what you are looking for!
1 lg. bunch green or red grapes
2 egg whites, slightly beaten
1 cup sugar
Wash & Dry grapes, break into small clusters. Dip each cluster into slightly beaten egg whites. Toss each cluster in bag with granulated sugar. Place sugar coated grapes on towel to dry.
The recipe came from the Greenville, SC Jr. League cookbook.
From your description, I think bw2082 has the right idea. Years ago Sunset magazine had an article about that exact technique. It featured mixed fruits and berries, strawberries, grapes, etc. I never tried it but I always thought it would be a great summertime treat.
