I am looking for a Shanghainese pastry in SF area. The name is Xie Ke Huang, literately means Yellow Crab Shell. I believe the name came from the appearance of the pastry since it looks like the color of a steamed crab shell.
I was able to buy it in Shanghainese restaurants and Chinese grocery stores in NYC. My BF loves it. He recently moved to San Francisco. I am wondering where he can get the same pastry. Thanks.
