It usually takes a few minutes, and both fresh and dried daylily should be blanched. Day lily, also called day lily, is one of people's favorite dishes. However, day lily contains colchicine. If the human body ingests colchicine, it will be oxidized in human tissues to produce colchicine. Colchicine is a highly toxic substance, which can poison human gastrointestinal tract and urinary system and seriously threaten health. If an adult eats 50 ~ 100 grams of fresh day lily at a time, it can cause poisoning. In order to prevent fresh day lily from poisoning, fresh day lily can be boiled in boiling water for a while, then soaked in clear water to remove most of the water-soluble colchicine. You can also cook fresh daylily thoroughly before cooking.

Second, how long does it take to soak the day lily?

Soak the dried day lily in warm water for 10~30 minutes, depending on the color and quality of the day lily. If it is a packaged manufacturer's day lily bought in a supermarket, it will be fine to soak it for more than ten minutes. If you buy it in the vegetable market, you should pay attention to the possibility of sulfur, soak it for a while, pour out the water and clean it for 2~3 times. The general principle of soaking is not to squeeze the daylily, which will affect the taste. If dried day lilies are used to make soup, the continuous high temperature will make the buds spread out, so that two day lilies can be used to form bubbles, so that the soup will not spread out and the taste will be more crisp.
