Edit: Never mind this recipe. I have found a much better recipe on a foodblog.
I'll post pictures later this month ( I'm in Hong Kong the next week).
Check the recipe here. Mine turned out beautifully. I made Cha Siu Chaan Bau with the same recipe! Great great great, I love it! And with the kitchenaid I don't have to knead the dough! Life can be so good..
