Eryngii Black Pearl, Pleurotes Noires, Black Kings, Shimofuri Hiratake
A sort of UFO in mushroom cultivation, this variety appeared a few years ago and quickly gained popularity in North America. Coming from a cross between a European variety and a Japanese variety, Black Pearl offer an excellent compromise between eryngiis and oyster mushrooms.
They have a wider base than that of oyster mushrooms, but less dense than that of eryngiis. Their rounded caps are reminiscent of eryngiis, with a color varying from light brown to dark tiger-brown depending on maturity and growing conditions. They grow in clusters and are easier to grow than eryngiis.
A variety belonging to the Pleurotus ostreatus family, Black Pearl offers a delicious flavor, close to that of oyster mushrooms with a more pronounced umami note. They are also very productive.
❄️ Storage: 1 month in the refrigerator.
