Jiangmi normal soak a day or so can be wrapped in rice dumplings, because the longer the glutinous rice soak to absorb water, the more viscous will be the better.
When the rice is soaking, you need to change the water to the rice every 4~5 hours so that the rice won't deteriorate and stink.
After soaking the rice for a day, if you are still not sure if you can wrap the dumplings, you can use your fingers to grind the rice, if you can easily crush it, then the stickiness will be enough to wrap the dumplings.
