What's the food culture in Nanjing?

Nanjing's relationship with duck goes back to the Ming dynasty, when the city served as the national capital from 1368 to 1421. The Hongwu Emperor's court, commemorated today at Ming Xiaoling on Zijinshan, reportedly consumed tens of thousands of ducks each year. The habit never left. By some estimates Nanjing processes over 100 million ducks annually for a metro area of roughly 9.4 million people. The signature preparation is yanshuiya, salted duck brined with Sichuan peppercorn and star anise, served cold and sliced at the counter. Skin should be pale gold, meat pink-tinged and faintly briny. Han Fu Chun near Fuzimiao has been selling it since 1866. A half-duck runs around 40 CNY, about $6 USD at current exchange rates. The flavor is restrained, almost austere, nothing like the lacquered sweetness of Beijing roast duck.

The Fuzimiao district around the Confucius Temple pulls the heaviest tourist foot traffic, and most stalls there price accordingly. Expect 20-40% markups over neighborhood rate, and tangbao that tend to sit in steamers too long, skins gone thick and gummy. Walk 15 minutes southeast to Laomendong instead. The renovated Ming-era lane has a commercial core, but the food vendors are solid. A stall near the south entrance sells duck-oil shaobing, a flaky flatbread baked with rendered duck fat, for 5 CNY. A few stalls down you might find gui hua tang yuan, sticky-rice balls in warm osmanthus-flower syrup, fragrant and mildly sweet in a ceramic bowl for 8 CNY. For the late-night slot, Shiziqiao food street near Hunan Lu runs from roughly 9pm to 2am. Grilled crayfish stalls fire up around 10pm. A plate of mala xiaolongxia costs 40-60 CNY depending on size.

Duck blood and vermicelli soup, ya xue fen si tang, is the anytime bowl that locals reach for when nothing else calls. Cubes of congealed duck blood sit in a cloudy pork-bone broth with sweet potato vermicelli, fried tofu puffs, and duck liver. The texture of the blood cubes is firm, slightly springy, with almost no iron taste when the shop keeps fresh stock. Hui Ji, with branches across the city, is the name most Nanjing residents mention first. That said, the cold-appetizer tradition here deserves equal attention. Gansi, dried tofu cut into hair-thin shreds and tossed with chicken broth, sesame oil, and sliced scallion, appears on nearly every restaurant's starter menu. Ma Xianxing near Zhongshan Lu has been open since 1845 and still sets the benchmark. The shreds should be so fine they tangle around your chopsticks. If they hold their shape, the knife work was lazy.

Most neighborhood restaurants operate without English menus, and staff rarely speak it. The Dianping app, China's dominant restaurant-review platform, carries photo menus for the majority of places. Point at the photo, hold up fingers for quantity. For popular spots like Nanjing Da Pai Dang on Zhongshan Lu, booking through Dianping or having your hotel's front desk call is the only reliable path, as the reservation line is Mandarin-only. Street food safety is straightforward. Eat where the wok is visible and the turnover is fast. Nanjing's food-hygiene inspection grades are posted on stickers near the entrance of licensed stalls, A being the top mark. Stick to A and B ratings and you will have no trouble. Mind you, tap water is not drinkable anywhere in the city. Nongfu Spring at 2 CNY from any convenience store is the default.
