The Chinese call them Baozi, I think. The Veitnamese version is the banh bao. These wonderful pillows of goodness remind me of my childhood. My parents and I would drive to Broadway & Argyle in Chicago to buy groceries and they would get me these goodies. I preferred the sweet char siu pork filling. My parents enjoyed the filling with the savory pork, shiitake mushrooms, chinese sausage and hard boiled egg. I think the ones with red dots on them are filled with sweet bean paste. Maybe one day I'll be brave enough to attempt these steamed buns.
