Black Pearl Oyster Mushrooms, Black Oyster Mushrooms, Black Kings, Shimofuri Hiratake
A bit of an oddity in the world of mushroom cultivation, this variety first appeared a few years ago in Japan and quickly gained popularity in North America. A cross between a European and a Japanese variety, Black Pearl mushrooms offer an excellent compromise between king oyster mushrooms and oyster mushrooms.
They have a wider stem than oyster mushrooms, but a less dense one than king oyster mushrooms. Their rounded caps resemble those of king oyster mushrooms, with a color ranging from light brown to dark brown with streaks, depending on maturity and growing conditions. They grow in clusters and are easier to cultivate than king oyster mushrooms.
A variety belonging to the Pleurotus ostreatus family, Black Pearl mushrooms offer a delicious flavor similar to that of oyster mushrooms, with a more pronounced umami note. They are also very productive.
❄️ Storage: 1 month in the refrigerator.
