1. soak the dried day lily in warm water 10~30 minutes, depending on the color and quality of the day lily when purchasing. 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.

2. The general principle of soaking is that you can't 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.
