Char Siu Bao, or barbecue pork buns, are a staple in dim sum restaurants. These steamed buns are filled with a sweet and savory barbecue pork filling. The dough is made from a combination of flour, yeast, sugar, and water, and is then filled with the char siu mixture. The buns are steamed until fluffy and the filling is heated through. The result is a soft and slightly sweet bun with a flavorful pork filling. Char Siu Bao is best enjoyed fresh and hot.
