Oyster mushrooms, also known as oyster caps, tree mushrooms, tree oyster mushrooms, summer oyster mushrooms, pleurotte and shimeji, are fan-shaped mushrooms that grow both wild and cultivated, usually on rotting tree trunks.
The cap can vary in color from pale gray to dark brownish-gray with grayish-white stems. While raw oyster mushrooms have a robust and slightly peppery taste, cooking mellows their flavor substantially.
Selecting and Storing Oyster Mushrooms
Oyster mushrooms are available year-round, particularly in specialty produce and Asian markets. Young oyster mushrooms - which are 1 1/2 inches in diameter and under - are considered the best. Canned oyster mushrooms are also available and should be rinsed before using.
