How to Store

The best way to store loose button mushrooms is to keep them in the refrigerator in a loosely closed paper bag wrapped in a damp cloth or laid out in a glass dish that is covered with a moist cloth. Whether you use a paper bag, a damp cloth, or a glass dish, it's worth avoiding all storage methods that leave the mushrooms stacked in one big clump. The less surface contact they have with one another the fresher they will stay. A great step to avoid clumping is to make a first layer of mushrooms inside your paper bag or on top of your damp cloth or glass dish, and then cover this mushroom layer with a paper towel. A second layer of mushrooms can then be placed on top of the paper towel. These storage methods will help preserve the mushrooms' moisture without causing them to become soggy and keep them fresh for several days. Once mushrooms have developed a slimy layer across their surface, they are not longer fully fresh.
