Dyeing method:
The dyeing method of purple/red/yellow is the same. Wash and chop these raw materials, then soak them in clear water, then put them in a pot and boil them with high fire. After the color comes out, filter it out, then rub the leaves in the pot hard and mix them with the filtered water before cooking. When the color comes out, it becomes a dye for dyeing. It is best to soak glutinous rice with this dye overnight. The coloring effect is the best.
The point is black. The maple leaves should be crushed together with the stems and put into water, and the ratio of maple leaves to water is1:15; Maple leaves soak for a day and a night, and the water turns yellow-green. After filtration, the water becomes a dye. Put this black dye in a pot and cook it to 70-80 degrees with high fire, then add glutinous rice and stir it slowly until it changes color. Be careful not to boil the dye. 70-80 degrees will do.
Finally, put these lewd glutinous rice into a steamer.
I hope my answer can help you and wish you a happy life.
