In Hong Kong last week I tried this for the first time and loved it. I don't know the Cantonese name: it was a steamed patty of minced pork, topped with crumbled salted fish, ginger, and scallion, with juices. I gather this is sometimes steamed separately and served with a side of rice and sometimes steamed atop the rice.
Is this an unusual or common dish, and where is a good rendition in the Bay Area, preferably SF, and preferably SF Chinatown? Is this the kind of dish that Utopia Cafe on Waverly does especially well?
If I wanted to make this at home, what is the salted fish called (or written) and where and how would I find it?
