These dumplings are typical chinese street-food snacks. They are filled with stir-fried savory turnip, also known as yam bean or jicama. The wrapper is made from wheat starch, also known as tang men fun and tapioca flour which give it a soft, translucent, slightly chewy bite and springy texture.
It's best to eat these dumplings fresh when they are made. However, you can keep for another 2 days by keeping them in an airtight container, put in the freezer and only steamed them just before serving.For vegetarian version, just omit the dried shrimps and meat and adjust seasoning with vegetarian oyster sauce or just extra sugar and salt.
