The flavour of oyster mushrooms is delicate and sweet. Some varieties smell somewhat like anise. Some have a fruity smell, like the yellow oyster mushroom. Glutamate is an amino acid found in mushrooms. This imparts a distinct umami flavour to the mushrooms. Umami, often known as savoury, is considered the fifth flavour. Low sodium dishes can benefit from the umami flavour. As a result, less salt needs to be added. In other words, mushrooms are a fantastic meat alternative.
