Boiled dumplings are cooked in boiling water. At this time, the water temperature is high enough to allow frozen dumplings to quickly condense the glutinous rice husk on the surface through high temperature, so that the stuffing inside can be better wrapped, and there will be no rotten or exposed stuffing halfway. When boiling with cold water or hot water, the water temperature cannot meet this requirement.
Tangyuan, also known as Tangtuan or Fuyuanzi, is not only one of the traditional snacks of the Han nationality, but also one of the necessary foods for the Lantern Festival, a traditional Chinese festival.

It is round in shape and tastes sweet and soft. It is generally made of glutinous rice flour, black sesame and white granulated sugar.
