I'm at my wits end. I've been trying to make cha siu bao (Chinese roast pork buns) for years -- YEARS! -- but have never managed to have any luck with the dough. I've tried every recipe I could get my hands on (Blonder, Yan, Wei Chun, etc.), but I have never managed to get that snow white, light, fluffy effect. One thing, though: I don't believe in recipes that specify anything other than cake flour. If anyone has a recipe -- not some piece of ridiculous internet flotsam, but a genuine recipe that produces restaurant grade results -- I would be immensely grateful to have it. General pointers are also welcome. Many thanks.
