I have enjoyed eating bao buns for a few years now around the city ... I’ve used a simple pork fillet sliced thinly and tossed in a hoisin sauce. All ingredients are available in the supermarket.
The fillings for bao buns are usually highly flavoured, colourful and complement the sweet buns. Roasted pork in sticky glaze is popular, combined with shredded spring onion and other vegetables.
