[Photo from visitgz.com]  As one of the typical snacks in Guangzhou, barbecued pork bun is also one of "Top Four Snacks" in Guangdong. The barbecued pork is chipped into pieces, added with seasons such as oyster sauce, covered by the flour and finally steamed in food steamers. The diameter of a barbecued pork bun is around 57 cm. One food steamer could accommodate three or four barbecued pork buns. Authentic barbecued pork buns adopt well-marbled barbecued pork. Also, after steamed, barbecued pork buns will be soft and smooth. The bun skin cracks a little bit, so as to give off the smell of barbecued pork.
