Mushrooms are extremely temperature sensitive. Farmers therefore pick and deliver to mushroom packers daily.
On average, mushrooms, which look bright and attractive should keep for 4 to 5 days in the refrigerator. To maximise the life and quality of your mushrooms:
- Refrigerate them immediately after you get them home
- Do not rinse the mushrooms until you are ready to use them
- Store in a porous paper bag – this is usually provided at the store
- Avoid airtight containers as they cause moisture condensation and speed up spoilage
- Do not stack heavy items on them – they bruise easily
- Do not store near pungent foods as mushrooms absorb strong odours
Before you use the mushrooms either:
- Wash them under cold running water
- Wipe them with a damp cloth or
- Wipe them with a soft brush / mushroom brush
This will remove any of the peat moss particles on them so they are ready for use.
Fresh mushrooms are not ideal to freeze, however if frozen when fresh they should keep for about two weeks. Alternatively, you could sauté them in a little butter, cool them and freeze in an airtight container, like this they will keep for up to a month.
Dried mushrooms may be kept in an airtight container in a cupboard for a long time however, it is better to keep them in the freezer where their freshness is preserved even longer.
