What are your favorite fillings?
Greek-style? Persian-style? California-style? Meat? No meat?
I've had some excellent stuffed grape leaves at restaurants, and I've also had some truly awful ones.
Our "favorite" family activity is to make large potfuls of dolma. We line the bottom of the pots with chunks of root vegetables which end up absorbing the goodness. Tedious to make, but they are so worth it.
They keep relatively well - in fact they are wonderful microwaved later... which tells me I should be able to find good ones which don't have the off-taste I often find in store-bought dolmas. And why are they so expensive?
