We have 4 grape plants that have grown like crazy this past year. The grapes are small and green right now, but the leaves are ready for picking. I picked just 25 and blanched them, following the directions here: http://greekfood.about.com/od/ingredientpreptechniques/a/abelofylla.htm
Dolmas is what we call stuffed grape leaves. Next time I'll try to pick the leaves earlier in June, as they were a bit tough and chewy. Or maybe I just needed to blanch them more than 3 minutes in boiling water? They were still very good!
Olivia ate 5 of them while rolling them up!!! Here's the basic recipe we followed: http://greatist.com/health/recipe-stuffed-grape-leaves
If you want to try to make them, and don't have a grape vine, you can buy canned grape leaves. I'd like to try to make them stuffed with meat and rice sometime in the future.
