1. Has tremella been smoked with sulfur? Sulfur smoked tremella can't be cooked. You can pick up the remaining tremella at home and smell it to see if there is a pungent smell, and then see if the color is unusually white. If it is not a normal bacterial smell or the color is very white, you should pay attention. Maybe tremella itself is smoked with sulfur and can't be eaten.

2. If the quality of tremella is good, but it will not rot after soaking for a long time, it may be caused by the long storage time of tremella purchased, so check the production time when purchasing.

3. There is no problem with the quality and production time of tremella, so it is a problem with the production process. It is best to soak in warm water instead of boiling water. After soaking your hair, you need to cut off the roots and simmer in a boiling pot.
