1. Cut the leaves of Zongzi and wash both sides. You can cook jiaozi in a big pot and take it out. Put some oil when cooking, and it's easier to open zongzi when eating.

2. The long glutinous rice used to make grey water dumplings is better, because the long glutinous rice is not very sticky, and the refreshing glutinous rice dipped in sugar is delicious. Grey water is soaked and filtered by plant ash water, and carbon can only be replaced by grey water. The grey water filtered with charcoal is black. Soak the washed glutinous rice in the grey water for the night. The mixed color of grey water and glutinous rice should be light yellow, so the boiled jiaozi is yellow. It is necessary to keep some jiaozi boiled in grey water.

After everything is ready, you can start making zongzi.

4. Put the wrapped grey water jiaozi into the pot. Cover all jiaozi with water. Add some grey water to boil jiaozi. When the fire boils, it can be adjusted to a moderate level. The water boiled in jiaozi turns yellow because it takes a long time. You can change the water in the middle and cook it again. The set meal is very small and will take two hours to cook. If it is bigger, it may take three hours to cook.

5. Serve with honey.
