Storing fresh shiitake mushrooms
Fresh shiitake mushrooms should be stored in a paper bag in the refrigerator. They should not be washed before storing and should be kept whole. The paper bag will absorb any moisture, keeping the mushrooms safe. If you don't have a paper bag, wrap the mushrooms in a paper towel and place them in a bowl in the refrigerator.
If you've already sliced the mushrooms, store them in an airtight container in the refrigerator. Sliced mushrooms should be used within three days, while whole mushrooms should be used within a week of purchase. If you are unable to use the mushrooms within a week, consider freezing them. However, fresher mushrooms tend to freeze better, so it is recommended to do this sooner rather than later. Before freezing, lightly sauté the mushrooms in butter until they are just cooked, or steam them whole for about five minutes.
If you have leftover fresh shiitake mushrooms from the farmer's market, you can dry them out and store them for longer. Spread the shiitake mushrooms on shelves so that the gills are directly exposed to sunlight. You can also string them using thread or fishing line and then hang and dry them in a breezy, dry spot. Once dried, the shiitake should be put into polyethylene bags, sealed, and kept in a dry, cool, dark place.

Sun Drying
Spread the shiitake mushrooms on shelves with the gills facing upwards and directly exposed to sunlight. You can also string them using thread or fishing line and hang them in a dry, breezy spot. The length of time required will vary depending on the weather conditions.
Dehydrator or Oven
If you want to speed up the drying process, you can use a dehydrator or your oven. First, slice the mushrooms, leaving as much of the stem intact as possible, ensuring it's not woody. Then, follow the instructions for your dehydrator, making sure the mushrooms are dried but still slightly flexible, not brittle. If using an oven, set the temperature to 200°F and keep the door ajar.
Air Drying
If you don't have access to a dehydrator or oven, you can air dry shiitake mushrooms. Place them on a cookie sheet in the fridge, with or without the stems, and leave them until they are dry and the caps are firm. This usually takes a few days.
Storage
Once your shiitake mushrooms are completely dried, store them in an airtight container in a cool, dry, and dark place. They can be stored this way for up to a year.
Reconstitution
Before using dried shiitake mushrooms in cooking, they must be reconstituted. Soak them in warm water for about 5 minutes before adding them to your recipe. Alternatively, if your recipe has enough liquid and cooking time, you can add them directly to the dish. Don't forget to use the soaking water for extra flavour!

Storing dried shiitake mushrooms
Dried shiitake mushrooms should be stored in an airtight container in a cool, dark place. They can be stored this way for up to a year, but for prolonged shelf life, you can store them in the refrigerator.
Dried shiitake mushrooms are traditionally believed to have the most intense flavor. They are produced by drying fresh shiitake mushrooms, which should be umbrella-shaped with the edges of the caps rolling inward. The stems and the undersides of the caps should be tan to white, and the mushrooms should not be wet.
There are several methods for drying shiitake mushrooms. One method is to spread the mushrooms on shelves so that the gills are directly exposed to sunlight. Alternatively, you can string them using thread or fishing line and hang them to dry in a breezy, dry spot. The length of time required will vary depending on the weather conditions. Another method is to use a dehydrator, following the manufacturer's instructions. Ensure that you dehydrate the mushrooms until they are light and dry but still slightly flexible and not brittle.
Once dried, the shiitake mushrooms should be cooled before being stored long-term. They can then be put into polyethylene bags, sealed, and kept in a dry, cool, dark place. If you are drying the mushrooms in an oven, set the temperature to 200°F and keep the door ajar.

Freezing shiitake mushrooms
Shiitake mushrooms are versatile ingredients that can be stored in a variety of ways. One popular method is freezing, which can help preserve their texture and flavour for up to six months. Here is a step-by-step guide to freezing shiitake mushrooms:
Preparing the Mushrooms:
Before freezing, shiitake mushrooms should be cleaned and sliced. It is important to use minimal water when cleaning to avoid soggy mushrooms. Use a slightly damp paper towel or kitchen cloth to wipe the mushrooms, or a mushroom brush. Remove the stalks as they tend to be tough and fibrous. You can set the stalks aside for use in soups, stews, or teas.
Cooking the Mushrooms:
Briefly cooking the mushrooms before freezing helps preserve their quality and flavour. Lightly sauté them in butter or olive oil until just cooked, or steam them whole for about 5 minutes. If using sliced or quartered mushrooms, steam them for about 3 minutes. You can also cook the mushroom slices at a high temperature until they are crispy, but be careful not to burn them. Cooking at a high temperature is particularly suitable for shiitake mushrooms as their skin is more robust than that of other varieties, such as oyster mushrooms.
Blanching the Mushrooms:
Blanching is an essential step before freezing shiitake mushrooms to preserve their texture. Freezing them uncooked will destroy their cellulose structure, resulting in a slimy texture. To blanch, place the mushrooms in a large pot of rapidly boiling water for about 3 minutes, or until they are barely cooked.
Freezing the Mushrooms:
Once cooked and blanched, allow the mushrooms to cool completely. Then, place them in a heavy freezer bag, making sure to use small quantities for individual servings. Store the mushrooms in the freezer for up to six months. When you're ready to use them, defrost them in the fridge before cooking.
Freezing is a great way to extend the shelf life of shiitake mushrooms and ensure you always have some on hand for your favourite recipes.

How long can shiitake mushrooms be stored?
The length of time that shiitake mushrooms can be stored depends on the method of storage and the temperature. Fresh shiitake mushrooms can last up to 10 days in the fridge if left unopened and stored correctly. Once opened, it is best to consume them within 7 days.
If you wish to store fresh shiitake mushrooms for longer, you can freeze them. Frozen shiitake mushrooms can be stored for up to 12 months in the freezer. However, once defrosted, they should be consumed immediately and not refrozen. To prepare shiitake mushrooms for freezing, wash and blanch them briefly in boiling water, then cool them in ice water before draining and placing them in freezer bags.
Another option for storing shiitake mushrooms is to dry them. There are several methods for drying shiitake mushrooms, including using a dehydrator, oven, or sunlight. Dried shiitake mushrooms can last for months, or even years, if stored in an airtight container in a cool, dry, and dark place. Before cooking, dried shiitake mushrooms need to be rehydrated in warm water for about 20-30 minutes.
It is important to note that mushrooms will dry out and lose weight the longer they are stored, so it is best to use them within a few weeks of purchasing if possible. Additionally, visual inspection is the most effective method to determine if shiitake mushrooms have gone bad. If they appear slimy or have significant colour changes, it is best to discard them. A sour or off smell is also an indication that the mushrooms have spoiled.
