Dried Shiitake mushrooms are readily available in Chinese markets. They are reconstituted in water before using in Chinese cuisine. Dried shiitake mushroom has a wonderful “umami” flavor which is great in a variety of dishes from soups to dim sum and dumplings. Dried shiitake mushrooms keep in the pantry or refrigerator for a long time, but make sure they are stored in a tightly sealed container or plastic bag so the smoky aroma stays intact.
