I just learned of this Hakka dish, seeming particularly popular in Singapore. They seem to be, essentially, taro/tapioca dumplings, boiled then stir-fried with other ingredients like mushroom and pork. They look like possibly the most delicious dish I might ever eat.
Alternative spellings of the traditional name are suin poon tzi, suan pan zi, sohn pan tzai, 算盘子.
Here's a link describing the dish: http://www.gourmetgarden.com.my/?p=4655
Has anyone seen these around Boston? At a restaurant or Asian food court?
