Soup dumplings are a traditional Chinese food, usually eaten on the Lantern Festival. You don't need to put sugar in the soup dumplings when you cook them, the dumplings themselves contain a lot of sugar, and if you put more sugar in them, it will cause them to become very sweet. Bring the water to a boil and then add the dumplings. Once the dumplings are in the pot, stir them gently with a spoon to avoid them sticking together. When the dumplings float to the surface, continue to cook for about 1-2 minutes until fully cooked and serve.
