Nice! From whence your colleague gotten that Dumpling from? The best Dumpling I've ever eaten was during my visit to a rural town in Central Northern Sarawak a few years ago. It could be the special rural recipe, it could be rural generosity, but my goodness it must be a good 400g of mouth orgasm.
The dumpling's from Melaka, I think they have the most famous nyonya dumplings. Sarawak's one I haven't try before.
