Sinseollo
Sinseollo or royal hot pot is an elaborate dish consisting of meatballs, small and round jeonyueo (전유어), mushrooms, and vegetables cooked in a rich broth in Korean royal court cuisine. The dish is a form of jeongol (elaborate chowder-like stew). It is served in a large bundt pan-shaped vessel with a hole in the center, in which hot embers are placed to keep the dish hot throughout the meal. Sinseollo is the proper name for the cooking vessel in which this dish is served, which has come to mean the actual dish as well. Sinseollo is a composite word of sinseon (신선; 神仙), "Taoist immortal spirit" and ro (로; 爐), brazier. Jeong Hee-ryang (정희량), a scholar in the court of Joseon Dynasty's King Yeonsan, turned to a hermit-like life in the mountains after being exiled and disillusioned from politics. He made a small brazier to cook his meals, a portable cooking vessel that would cook various vegetables in a single pot. He disappeared in the mountains and legend says he became a sinseon, so the cooking vessel was named "brazier for a sinseon". Sinseollo is also called yeolguja tang, which literally means "a tang (soup) that makes a mouth happy".
