Soaking tremella is very simple. First soak the tremella in cold water for three or four hours, then pick up the residue from the root and wash it with cold water several times. Before cooking, soak tremella in small water, put the root of tremella upward, completely soak tremella in water, and then let it stand for about 30 minutes.

In addition, most families use hot water to soak tremella. Because hot water bubbles bubble faster and can be applied quickly, this method is loved by some housewives.
