These are a sticky and fun snack that my mom sometimes makes. I'm not sure what exactly they are called so I call them glutinous rice flour dumplings. :) The shell is made of glutinous rice flour (also known as sticky rice flour), tapioca starch, water and a little bit of salt. The glutinous rice flour makes it a bit sticky and chewy. The inside is just a mixture of pork, shrimp and black fungus mushrooms. They are steamed up and served with sweet and sour fish sauce.
If they are not being eaten immediately, then we usually wrap them up in banana leaves before steaming them so that they can be stored more easily.
