-Combine all of the ingredients in a bowl and mix thoroughly with a spoon or with your hands. Chill in preparation for dumpling filling.
-To form the dumplings, take a dumpling wrapper and add a mound of filling in the middle. Wet the outside edge and press together in a half-moon to seal. Crimp the edges (see the video for a demonstration).
-To cook, steam in a conventional steamer for about 15 minutes, or until the juices of a poked dumpling run clear. In a steam oven at 100 C, it will take just under 10 minutes.
