After tying the rope and wrapping the zongzi, the tightness of the rope should be controlled, not too loose or too tight. If tied too tightly, the glutinous rice and ingredients in the zongzi will expand during heating, which may break the zongzi. But at the same time, it should not be too loose, otherwise a lot of water will enter the inside of zongzi when cooking, which will make the leaves of zongzi and rice blister seriously and leak rice.

What kind of rope is used for 6 packs of zongzi? Hemp rope, cotton rope or zongzi leaves.

When wrapping zongzi, try to use rope such as hemp rope, cotton rope or zongzi leaves that will not produce harmful substances to human body. Such as plastic rope and chemical fiber rope, will produce harmful substances when heated at high temperature. If they are used to wrap rice dumplings, harmful ingredients will enter the rice dumplings, which will cause certain harm to health and may also cause food poisoning after eating. Therefore, it is recommended to choose pure natural materials, non-toxic and harmless ropes.
