Churchkhela is a Georgian candy sort of like fruit rollups with nuts in the middle. Since winemaking began in the Republic of Georgia and has been going on for thousands of years, the question was what do you do with all those grape skins when you're done pressing the juice out of them for the wine? Well, Georgians boil up the white grape skins, thread some walnuts or hazel nuts onto a cotton string, add a little corn and wheat flour to the skin juice, dip the nuts into the skin juice once, let it dry, then twice and let that dry. Each region of the country does things a little differently in both the wine and the churchkhela they make. Some of the churchkhela varieties are shown in the following pictures. BE SURE TO PULL THE STRING OUT BEFORE EATING.
I don't know where you can get it in the US, so you'll most likely have to make it yourself. You should be able to following the gallery instructions. If you go to the Republic of Georgia, it's sold in roadside stands everywhere.
