1, cooking before not soaking: fungus soup is not sticky, it is very likely that when cooking fungus soup is not soaked fungus soup in advance, because after soaking the fungus, in the cooking of the fungus, it can be inside the composition of the material completely released, so the fungus soup is not sticky, it is very likely that there is no fungus soaked in advance.

2, the quality is not good: usually as long as the steps of cooking fungus is not used incorrectly, then it is possible to cook the fungus sticky, if the fungus is not sticky, it is likely because the quality of the fungus is not good enough, because only safe and sulfur-free high-quality fungus can be out of the gelatin.

3, too much water: cooking fungus soup, if the water put too much, then it will also lead to the fungus is not thick, because the water is too much, it will lead to the lack of gelatin fungus, so it is not easy to cook out of the fungus thick.
