Shanxi Province, China

Shanxi cuisine is most well known for its extensive use of vinegar as a condiment and for its noodles. A dish originating from Taiyuan, the provincial capital, is the Taiyuan Tounao (太原头脑, literally "Taiyuan Head"). It is a soup brewed using mutton, shanyao (山药, Chinese wild yam), lotus roots, astragalus membranaceus (黄芪, membranous milk vetch), tuber onions, as well as cooking liquor for additional aroma. It can be enjoyed by dipping pieces of unleavened cake into the soup, and is reputed to have medicinal properties.
