The rice used to make zongzi should be salted, 1-2 tablespoons per kilogram of rice is enough.
Glutinous rice needs to be soaked for a period of time before making rice dumplings. You can soak it in water at 30°C for about 40 minutes, then drain it for about half an hour, or you can soak the glutinous rice in clean water, but the time should be at least Guaranteed 3 hours.
During the process of soaking the rice dumplings, water will enter the rice dumplings through the cells. The longer the soaking time, the more water will enter the cells of the glutinous rice, which will burst the cell walls of the glutinous rice. Completely release the stickiness of glutinous rice, making the rice dumplings more sticky. Then add an appropriate amount of alkali and salt and mix well before wrapping.

The glutinous rice soaked in this way will be made into rice dumplings that are white and shiny in color, have a unique aroma of rice dumplings, have a moderate taste and viscosity, and are refined but not rotten.
