Shiitake mushrooms are known for their deep savoury flavour and meaty texture. Some consider them the foundation of many Asian dishes as they are used to boost the umami quality of the plate. Dried shiitake mushrooms can be stored for long periods of time making them an attractive year round alternative to fresh mushrooms. Store them in an air tight container, in a cool and dry place. Soak in hot water before use or add them to your soup as it simmers.
