I saw this idea in a book by Jamie Oliver once , and I was really interrested on how it would work, becouse if you buy beautiful fresh grapes then why would you freeze them, but it really works!! The inside of the grapes change to a sorbet like consistensy and are a great complement to a warm summer day.
The best way to eat frozen grapes is with some good quality hazelnut chockolate or dark Varlhrona chockolate and limonchello snaps.
