Char Siu Bao, also known as steamed BBQ pork buns, are a must-have dim sum item. These fluffy and soft buns are filled with a sweet and savory BBQ pork filling. The filling is made by marinating pork in a flavorful sauce, then roasting it until tender and caramelized. The buns are steamed until they become light and airy, creating a perfect contrast with the rich and flavorful pork filling.
