This was one of the dishes I had during dim sum with coworkers.

Cha siu bao or char siu bao is a Cantonese barbecue-pork-filled bun (baozi). The buns are filled with barbecue-flavored cha siu pork. They are served as a type of dim sum during yum cha and are sometimes sold in Chinese bakeries. Cha siu refers to the pork filling; the word bao simply means “bun”. Although visually similar to other types of steamed baozi, the dough of steamed cha siu bao is unique since it makes use of both yeast and baking powder as leavening. This unique mix of leavening gives the dough of cha siu bao the texture of a slightly dense, but fine soft bread. Encased in the center of the bun is tender, sweet, slow-roasted pork tenderloin. This cha siu is diced, and then mixed into a syrupy mixture of oyster sauce, hoisin sauce, roasted sesame seed oil, rice vinegar, shaoxing wine or dry sherry, soy sauce, sugar and cornstarch.
