2-6 hours. When making steamed dumplings, the soaking time of glutinous rice can be adjusted according to your own needs, but it is generally about 2 hours, and it takes 2 hours for glutinous rice to soak in water. The longer the glutinous rice is soaked, the better. The longer the soaking time, the greater the water absorption. The cooked glutinous rice will be soft and sticky. At this time, it will be more difficult to mix the ingredients, and the steamed dumplings will be waxy and not very delicious. Therefore, it is suggested that the soaking time of glutinous rice should not exceed 6 hours, and it is best to ensure that it is within 6 hours, so that the steamed dumplings cooked will not taste too glutinous, and it is not necessary to pay special attention to the influence of firepower on the softness of glutinous rice when cooking.
