Black Mushrooms
Thai: ??????? (het hawm)
Black Mushrooms are available fresh or dried at most Chinese markets. This is a very commonly eaten mushroom in Asia. If you purchase dried, pre-soak in room temperature water for at least an hour before cooking. The water used to soak the mushrooms can also be used as a soup base.
Storage: Fresh mushrooms will go bad quick, so use within a day or two. Dried mushrooms will last forever if you keep them dry in the cupboard.
