At Chiu Quon Bakery (@chiuquonbakery), the oldest bakery in Chicago’s Chinatown, bakers create Hong Kong-style pastries, including their most popular item: char siu buns. Chiu Quon co-owner Matthew Chiu says that while multiple people at the bakery know how to make the dough for the buns, only one man gets the honor, head baker Jin Zhao. About 10,000 buns are made a week.
