I had made a video of my mom picking grape leaves in June of 2011, and I finally put together a second video showing how to roll and cook them (below). (I use jarred grape leaves in the second video.)
We always referred to these rice and onion (plus other great stuff) stuffed grape leaves as dolma, but the more appropriate name is yalanchi sarma, which refers to a meatless filling wrapped in some kind of leaf. We still call them dolma, which really just means that something is stuffed. They are an awesome food and I hope you'll give them a try soon!
These are grape leaves growing off of shrubs in my back yard. They apparently planted themselves.
