Agaricus bisporus, commonly known as the button mushroom, is a species of edible mushroom that belongs to the Agaricaceae family. It is one of the most widely consumed mushrooms worldwide and is cultivated commercially on a large scale. Frozen Agaricus bisporus refers to this mushroom variety that has been frozen to extend its shelf life and preserve its quality. It's worth noting that frozen mushrooms should be thawed before use, and excess moisture should be removed to prevent sogginess. They can be cooked in a similar manner to fresh mushrooms, either sautéed, grilled, roasted, or used in other cooking methods as desired. Overall, frozen Agaricus bisporus provides a convenient option for enjoying this popular mushroom variety year-round, even when fresh mushrooms may not be readily available.
Frozen Agaricus bisporus typically has a white to light beige coloration, although it can vary depending on the stage of maturity. The mushroom has a fleshy texture and a mild, slightly earthy flavor. The cap of the mushroom is usually round and convex-shaped when young, gradually flattening out as it matures. The cap can reach a diameter of around 2 to 5 centimeters (0.8 to 2 inches) or more.
Underneath the cap, there are numerous tightly packed gills that start off pink and mature to a dark brown color. These gills produce the mushroom's spores, which are an important part of its reproductive cycle. The stem of Agaricus bisporus is cylindrical and can vary in length, depending on the stage of growth and cultivation practices.
The nutrition facts of frozen Agaricus bisporus, also known as button mushrooms, can vary slightly depending on the specific brand or method of cultivation.
