Khorkhog is a traditional barbecue that is prepared in large milk jugs together with heated stones. The meat and the stones are placed in the containers, and the water is then added, creating steam that cooks the meat. Invented by nomadic Mongolian tribes, khorkhog is usually made with bone-in cuts of mutton, lamb, or goat meat, as well as vegetables such as cabbage, onions, potatoes, and carrots.
