Shengjianbao is a type of pan-fried pork bun that is crispy on the outside and juicy on the inside. The buns are typically filled with pork and a savory broth, and are often served with a side of vinegar and ginger. One of the best places to try Shengjianbao in Shanghai is at Yang's Fry Dumplings, a local chain with several locations in the city.
