Have you seen such giant steamed bun (or "Pau" or "Bao") before (on the right)? The diameter measures about 20 cm (or 8 inches)!
Below is a large or regular size bun bought from another shop. The dough is very soft and thin, the best I've tried so far.
The filling is made of barbecued pork (or "char siu") with some chunks of lard. Every time I eat one of these, I would carefully pick the lard out and throw them away.
I've been wanting to make my own buns from scratch and omit the lard without compromising the taste! I need to make some extra research first before I start to cook :) I'll let you know how it went, lol!
