There are many conflicting opinions on how to clean mushrooms safely. Some sources claim that mushrooms should not be washed, while others argue that a quick rinse is sufficient. The method of cleaning mushrooms depends on the type of mushroom and how it will be used. Wild mushrooms, for example, may require a more thorough cleaning due to the presence of dirt or grit. Cultivated mushrooms, on the other hand, are often grown in sterile environments and may only need to be brushed off with a dry towel or mushroom brush. When using water to wash mushrooms, it is important to avoid soaking them for too long as they can absorb water, affecting their texture during cooking.

When to wash mushrooms

There are conflicting opinions on whether mushrooms should be washed or not. Some sources claim that mushrooms should never be washed, while others argue that it is safe to do so. However, the general consensus is that the decision to wash mushrooms depends on how you source them and how you intend to use them.

If you are consuming the mushrooms raw, it is generally recommended to wash them first. This is especially important if you are using wild mushrooms, as they may harbour bugs or have dirt and grit from the forest floor. Wild mushrooms, such as the wild hen and chanterelles, often require a more thorough cleaning. It is recommended to cut these mushrooms into pieces before submerging them in water and agitating them to remove any dirt and grit.

On the other hand, cultivated mushrooms grown in sterile environments, such as those typically purchased at grocery stores, do not need to be washed. These mushrooms are grown on sterile manure, which is the "dirt" that clings to them. A simple brush-off with a dry towel or mushroom brush is usually sufficient to remove any loose dirt.

If you are still concerned about the cleanliness of your cultivated mushrooms, a quick rinse under cold water followed by a gentle rub with your fingers or a soft towel can help dislodge any stubborn particles. Just be sure not to let the mushrooms soak for too long, as they can absorb water, which may affect their texture during cooking.

In summary, the decision to wash mushrooms depends on the type of mushroom and your intended use. Wild mushrooms and raw preparations generally require washing, while cultivated mushrooms from sterile sources can be simply brushed off. Remember to always inspect your mushrooms and ensure they are free of visible dirt before cooking or consuming them.

How to brush mushrooms

When it comes to cleaning mushrooms, there are a few different methods that can be used, depending on the type of mushroom and how it was sourced. Here is a detailed guide on how to brush mushrooms:

Brushing Mushrooms:

Firstly, identify whether your mushrooms are cultivated or wild. If you purchased them from a grocery store, they are cultivated. Wild mushrooms, foraged or bought from a farmer's market, tend to have less grit and are less hardy, so they require careful brushing to prevent damage.

Use a mushroom brush or a dry towel to gently brush off any visible dirt. You can also cut off any sections of the mushroom that are holding dirt, usually the base or end of the stem. If the mushrooms are relatively clean, this may be all you need to do.

Washing Mushrooms:

If your mushrooms are particularly dirty, you may need to wash them with water. Fill a large bowl with cold water, adding a tablespoon of salt per 4 cups of water if you are concerned about tiny creatures. Swirl the mushrooms in the water for about 10 seconds to loosen any remaining dirt. Immediately remove them and pat them dry with a lint-free or cotton towel.

Other Considerations:

Some sources suggest that it is unnecessary to wash cultivated mushrooms due to their sterile growing conditions. However, store-bought mushrooms often arrive with a peaty-smelling growing medium clinging to their caps, so rinsing them briefly under cold water or wiping them with a damp towel can help remove any stubborn particles.

If you plan to eat the mushrooms raw, be mindful that they can absorb water, potentially affecting their texture. In this case, brushing may be a better option.

Mushroom Varieties:

Certain wild mushroom varieties, such as Chanterelles, can be extremely dirty and require more aggressive washing. On the other hand, Morels have a unique honeycomb texture and should be brushed and halved lengthwise before being swooshed in a bowl of water and dried in a salad spinner.

Remember to always examine your mushrooms after cleaning to ensure they are free of visible dirt.

Washing wild mushrooms

There are various methods for washing wild mushrooms, and the right one depends on the type of mushroom and how dirty it is. Wild mushrooms are harvested from unsterile environments that can host leaves, twigs, pine needles, dirt, and bugs.

If your mushrooms are covered in dirt, you can fill a large bowl with cold water and add a few mushrooms at a time. Swirl them around for about 10 seconds, then lay them out to air-dry on a clean, lint-free towel. If there is still dirt on the mushrooms, use a damp paper towel to wipe them off.

Another method is to rinse the mushrooms one or two at a time under a cold tap and rub them gently with your fingers or a soft towel to dislodge any stubborn particles.

For chanterelle mushrooms, you can use either the paper towel or water rinse methods. However, if you see tiny bug holes in the stem, add a tablespoon of salt to 4 cups of water and let the mushrooms soak for 20 minutes before drying them.

If your mushrooms are relatively free of dirt, you can simply wipe them with a damp paper towel or clean kitchen towel to remove any remaining dirt.

Keep in mind that mushrooms are like little sponges, so it's important not to let them soak for too long, as they will absorb water, which can affect their texture when cooked.

Soaking mushrooms

When soaking dried mushrooms, it is generally recommended to use warm or room temperature water. This helps to soften the mushrooms without affecting their flavor. The soaking time can vary depending on the type and thickness of the mushrooms but typically ranges from 20 to 30 minutes, or even longer for thicker varieties. Some sources suggest that using hot water can affect the flavor of the mushrooms, making them less aromatic and flavorful. However, hot water can be used if you are in a hurry or dealing with thicker mushrooms.

For fresh mushrooms, the general consensus is to avoid soaking them for extended periods. Fresh mushrooms are like little sponges and can easily absorb water, which can impact their texture and cooking properties. When washing fresh mushrooms, a quick rinse or a brief swirl in a bowl of cold water is usually sufficient. They can then be patted dry with a towel before further preparation.

It is worth noting that the decision to soak or wash mushrooms also depends on personal preference and the intended use. Some cooks prefer to brush off any dirt or debris from fresh mushrooms, especially if they are foraged or wild mushrooms, as they can be more delicate and expensive. However, others argue that a quick rinse or soak can help ensure the mushrooms are clean and safe to consume, especially if they are to be eaten raw.

Additionally, the soaking liquid obtained from reconstituting dried mushrooms can be used as a flavorful addition to various dishes. It can be added to soups, stews, sauces, or even used as a substitute for chicken stock in vegan or vegetarian recipes.

Drying mushrooms

To dry mushrooms, you don't need any special equipment. While you can use a dehydrator or an oven, it is also possible to air dry them. To air dry, place the mushrooms in an open container with good airflow, such as a mesh colander, and leave them out to dry for about a week. They are ready when they are completely dry to the touch and do not give at all when squeezed.

If you want to speed up the process, you can partially dry the mushrooms in the oven first and then finish air-drying them on a sunny windowsill. However, it is important to note that drying times may vary depending on humidity levels and the size of the mushrooms.

Once the mushrooms are fully dried, you can store them in a cool, dry place for up to two years.

Alternatively, if your mushrooms don't dry well, you can cook and freeze them instead. Sauté them in butter, salt, and pepper, and add onion, garlic, or shallot for extra flavour. Let them cool, then spoon them into freezer bags and place them in the freezer. Frozen mushrooms can be added to sauces, soups, casseroles, and stir-fries.

Frequently asked questions

It is generally safe to wash mushrooms, contrary to popular belief. The concern is that mushrooms will absorb water, impacting their texture and flavour. However, this effect is minimal, and any excess water will cook out.

Use cold water and gently rub the mushrooms with your fingers or a soft cloth to dislodge dirt. Avoid soaking them for too long. After washing, pat them dry with a clean towel and let them air-dry before cooking.

Store-bought mushrooms are cultivated in sterile environments and are generally clean. A quick rinse under cold water or a gentle brush to remove any loose dirt is sufficient.

Wild mushrooms may have dirt, grit, or bugs, so they require more thorough cleaning. Soak wild mushrooms in salty water to remove any critters, then rinse and pat them dry. Cut larger wild mushrooms into pieces before washing to ensure effective cleaning.

Use a mushroom brush or a soft-bristled brush to gently clean dirt from the crevices of mushrooms. You can also peel the mushrooms or cut off any sections holding dirt, such as the base of the stem.
