2. 1 kg of glutinous rice corresponds to 2 kg of water, and the soaking time of glutinous rice should not be less than 5 hours or more, because 5 hours is enough to completely soak glutinous rice. If the soaking time of glutinous rice is too short, the glutinous rice will absorb less water, which will lead to rice leakage, while if the soaking time of glutinous rice is too long, the glutinous rice will be soft and the cooked glutinous rice will not taste soft.
