2, the method of soaking glutinous rice, if normal, the sticky glutinous rice, the more delicious jiaozi. As long as the method of soaking rice is correct, the longer the rice wraps the zongzi, the better, at least about 3 hours. We soak the glutinous rice with clear water, then change the water 2-3 times a day, and then make zongzi after soaking for 2-3 days. Because glutinous rice has been soaked in water for a long time and absorbed enough water, the sticky components in glutinous rice are released, making zongzi extremely sticky and soft. Don't worry about soaking glutinous rice for a few days. In fact, as long as the water is changed every day, the glutinous rice will not go bad. Add enough water, otherwise the glutinous rice will be exposed to the air after absorbing enough water, and the rice grains will be pulverized and easily deteriorated. The zongzi steamed by this method is delicious and soft, but it takes a long time.
