Warm up with Shaanxi’s hearty mutton and flatbread soup

羊肉泡饃：冬日御寒暖胃佳品

Each winter, when the harsh winds whistle across the dusty plains, the people of Shaanxi province know it’s time to warm up withyangrou paomo,or flatbread in mutton soup.

Finely cooked with tender bread and rich (but not greasy) mutton fat, the fragrant and hearty dish has sated many a stomach on a winter’s day, including that of the well-known foodie and poet Su Dongpo (蘇東坡).“Flatbread in mutton soup is foremost in my heart out of all Shaanxi dishes,” he wrote during his exile in the 11th century.

The dish is believed to have originated from the “mutton stew(羊羹)” served in royal households as early as the Western Zhou dynasty(1046 – 771 BCE), according to theBook of Rites. At that time, nobles began partaking of mutton soup as an imperial ritual. Traditional medicine expert Li Shizhen (李時(shí)珍) once noted that mutton is bene ficial for regulating theqiinside the spleen and stomach, as well as expelling cold air from the body.

Yangrou paomofirst took shape during the armed rebellion against the Tang dynasty (618 – 907) led by An Lushan(安祿山) and Shi Siming (史思明)from 755 to 763. To help quell the rebellion, the Tang brought in Tajik mercenaries, who were stationed in the capital, Chang’an (now Xi’an).These soldiers were fond of eating hard naan bread moistened with mutton soup, as Chang’an was located close to the pastures and mutton trading routes in China’s northwest. As the soldiers began to interact with the locals, their cooking methods were generally embraced by commoners, especially local Muslims.

Though historically,yangrou paomowas a folk dish enjoyed by commoners,the cooking process requires precision to get the taste just right. High-quality mutton should be thinly cut and cleaned, and brought to boil with seasonings like scallion, ginger, and fennel. The bread must be “pulled,torn, pinched, and shaken” into pieces the size of soybeans, according to a new cooking standard published in 2016 by the Xi’an government.

It’s considered amateurish to stir the soup with chopsticks before eating.Shaanxi natives eat the bread close to the rim of the bowl first to preserve the delicate taste of the liquid, and end by drinking the soup to refresh the spirit.

For tourists who want to try authenticyangrou paomo, the restaurant Tong Sheng Xiang in Xi’an, founded in 1920, uses a cooking method that is listed as a national intangible cultural heritage item. Lao Sun Jia, another Xi’an restaurant, claims its flatbread and mutton soup as “the bestyangrou paomounder heaven.”
