Ermmm...I don't really know what you call this. But here we call it pau (po maybe??). Anywho, it is a puff thingy filled with yummy-some goodies inside ie. this one is filled with red bean paste. :D My favorite! Some other fillings would typically be coconut, nuts, butter, chicken curry, and green bean paste.
**Sorry for the awful quality, took them with my phone :)
Edit: Oh now I just realized these are dumplings XDD
Are you wearing pink today?
