About King Oyster
King Oyster mushrooms (Pleurotus eryngii) are the largest of the oyster mushroom family and are considered the most gourmet. Unlike other oyster varieties, King Oysters grow as individual mushrooms rather than clusters, developing thick, meaty stems that can be sliced and cooked like scallops. Their mild flavor and substantial texture make them a favorite among vegetarian chefs.
