1. Improper selection and handling of tremella: The tremella varieties selected are not of good quality and fresh, or the tremella is not fully soaked before cooking, which will affect the gum yield of tremella. High-quality fresh tremella is easier to cook.
2. The cooking time and heat are wrong: it takes enough time for the golden fungus to cook the gum. If the cooking time is not long enough, the gum will not be completely released. In addition, too much or too little heat will also affect the gum production of tremella.
