These oysters are cultivated, and are thus, very clean. Averaging between 20-30 pieces per pound. We suggest not washing these before use, but rather, simply wipe any matter off the mushrooms before preparation. Oysters are typically a wet mushroom, so note this upon receipt. Also known as Tree oysters or Pleurotus, their light gray to soft brown caps fan-out in oyster shell fashion, thus adding credence to their names’ origin. They are terrific in cheese based soups, deep fried and served with cocktail sauce, or cooked lightly and served upon Asian braising greens. Store mushrooms between 32-34 degrees F, in a well-ventilated box with a paper or cardboard cover, and keep dry. Mushrooms neither produce, nor are affected by ethylene gas. Store away from odoriferous foods.
