Fresh mushrooms should be stored with cool air circulating around them. Therefore, they should be placed on a tray in a single layer, covered with a damp paper towel and refrigerated for up to 3 days. Before use, they should be wiped with a damp paper towel or, if necessary, rinsed with cold water and dried thoroughly. Mushrooms should never be soaked because they absorb water and will become mushy. Trim the stem ends and prepare according to directions.
Canned mushrooms are available in several forms including whole, chopped, sliced and caps only.
Frozen or freeze-dried mushrooms are also available. Dried mushrooms are available either whole or in slices, bits or pieces. They should be stored in a cool, dry place for up to 6 months. Mushrooms are one of nature's most versatile foods and can be used in hundreds of ways and cooked in almost any way imaginable.
