Precautions for Cooking Dumplings
Many frozen dumplings are not easy to cook, so you should pay attention to the way you cook these dumplings. When cooking frozen dumplings, it's best to boil them "three times," that is, three times after putting them in, adding a spoonful of cool water each time. This can prevent the dumplings from floating during the cooking process, the phenomenon of "fake cooked".
