Khinkali are Georgian soup dumplings. In the high Caucasus mountains of Kazbegi, the khinkali are usually stuffed with lightly spiced meat.
This filling can be made of ground beef, pork, or a mixture of both. Make sure there is some fat in the filling; if the meat is very lean, add an extra 2 tablespoons of butter or oil to the mixture. Meat khinkali are supposed to be juicy and your aim is to trap some of the rich broth inside the dumplings.
