Store mushrooms in a paper bag in the refrigerator. Avoid airtight containers that can collect moisture and cause the mushrooms to spoil faster.
For best quality use fresh mushrooms within a week. Canned mushrooms usually have a ‘best by’ date on the can. Dried mushrooms keep their quality for up to a year in an airtight container in a cool, dry place.
Dirt on mushrooms is normal. Clean mushrooms just before using. Use a soft brush or slightly dampened paper towel to brush off the surface or rinse very briefly under cold, running water and pat dry.
Cooked mushrooms can be frozen. For best quality, use within 1 month.
