What You'll Learn

Wild vs cultivated mushrooms
Mushrooms are widely used for culinary and medicinal purposes. They are prized for their distinctive flavours, textures, and nutritional value. While cultivated mushrooms are crucial for everyday culinary use due to their availability and uniformity, wild mushrooms are celebrated for their complex and varied flavour profiles.
Wild Mushrooms
Wild mushrooms are highly prized in gourmet cooking for their robust and distinctive tastes. Popular varieties include boletes, porcini, and chanterelles, which are known for their earthy, nutty, and sometimes fruity notes. These flavours can vary significantly depending on the natural habitat and the soil they grow in. Wild mushrooms typically access a wider range of nutrients from the soil compared to cultivated mushrooms. They are often sought after by foragers and chefs alike for their unique flavours. However, it is important to correctly identify wild mushrooms before consumption, as some species are toxic or at least indigestible when raw. Incorrect identification can lead to fatal poisonings.
Cultivated Mushrooms
Cultivated mushrooms, such as the common white button, shiitake, and portobello, offer a more consistent taste and texture due to the controlled environment in which they are grown. They have a milder flavour, making them versatile in a wide range of dishes. Cultivated mushrooms are crucial for everyday cooking due to their availability, uniformity, and mild taste. They are grown in controlled environments, ensuring a consistent nutrient profile, which is beneficial for those seeking predictable dietary content. Agaricus bisporus, or the common button mushroom, dominates the edible mushroom market in North America and Europe.
Sustainability and Environmental Impact
The harvesting of wild mushrooms can have minimal environmental impact when done sustainably, preserving biodiversity and the natural ecosystem. However, overharvesting poses risks, including the disruption of local flora and fauna. Mushroom cultivation, on the other hand, can require significant resources such as water, energy, and space. Innovative farming techniques, such as vertical farming, are helping to reduce the ecological footprint of mushroom cultivation. Both methods, if managed responsibly, offer sustainable ways to meet the growing demand for mushrooms.

How to wash different types
There are several different methods for washing mushrooms, and the best method depends on the type of mushroom.
Wild Mushrooms
Wild mushrooms are harvested from the wild and can be found growing on the side of a tree, at the base of a tree, or even in your driveway or yard. These mushrooms grow in unsterile environments, so they may be covered in leaves, twigs, pine needles, dirt, or bugs. As such, they require a more thorough cleaning than cultivated mushrooms. Wild mushrooms that are relatively clean can simply be brushed off with a dry towel or mushroom brush, or you can cut off any sections of the mushroom that are holding dirt, generally the base or end of the stem.
Wild mushrooms with a lot of dirt in their crevices and creases may need to be soaked in order to be cleaned properly. To clean wild mushrooms, start by cutting the mushrooms into pieces. Then, submerge the pieces in water and agitate them to remove any dirt or grit. Finally, pat the mushrooms dry between clean kitchen towels.
Some common types of wild mushrooms include:
- Morel
- Hen of the Woods
- Chicken of the Woods
- Puffballs
- Chanterelles
Morels, in particular, are known for their honeycomb texture, which can collect dirt and sand. To clean morels, start by brushing them with a mushroom brush or a soft toothbrush. Then, rinse the mushrooms under running water and use a brush to remove any remaining grit. Finally, dry the morels in a salad spinner.
Chanterelles are wild summer mushrooms that are either very clean or covered in forest floor debris, depending on where they were collected. If the chanterelles were foraged from the wild, check for tiny bug holes at the stem end. If there are no bug holes, wash them following the method for wild Hen of the Woods mushrooms described above. If there are bug holes, add salt to the washing water (1 tablespoon per 4 cups of water) to evict any tiny creatures.
Cultivated Mushrooms
Cultivated mushrooms are grown in sterile environments, so they are generally cleaner than wild mushrooms. Cultivated mushrooms can be brushed off with a dry towel or mushroom brush, or you can cut off any dirty sections of the mushroom. If the mushrooms are very dirty, they can be rinsed under cold water and dried with a paper towel or kitchen towel.
Some common types of cultivated mushrooms include:
- Button
- White
- Brown Cremini
- Shiitake
- Oyster
- Portobello
- Maitake
- Enoki
- King Trumpet
- Blue Oyster
- Lion's Mane
- Italian Oyster
Oyster mushrooms and maitake mushrooms are very delicate, so they require a gentle touch when cleaning. Trim their ends, then soak the mushrooms for five minutes. Drain the mushrooms and dry them carefully, using a salad spinner or a thin cotton dish towel.
Portobello mushrooms are simply adult cremini mushrooms, so they can be washed using the same method as other cultivated mushrooms. However, it is a good idea to remove the gills on the underside of the cap first, as they can retain water. Use a serrated spoon to scoop out the gills, then pat the cap dry with a kitchen towel.
Additional Tips
- Wash mushrooms just before you are ready to cook them, as unwashed mushrooms last longer in the refrigerator.
- If you are searing or grilling a mushroom, it is best to wipe or brush the mushroom instead of rinsing it, as the extra water can affect the flavor and texture.
- To remove excess water after rinsing mushrooms, place them in a salad spinner lined with paper towels or a dish towel and give them a few spins. You can also lay the mushrooms on a double layer of cotton dish towels and pat them dry.

When to wash
Wild or foraged mushrooms
Wild mushrooms are often caked in dirt, pine needles, and even insects. Foraged mushrooms should always be washed to remove any dirt and insects. You can wash them by dunking them in a bowl of water and vinegar, scrubbing them with a soft-bristle brush, and then rinsing them with fresh water.
Cultivated mushrooms
Cultivated mushrooms are typically grown in sterile environments with pasteurized compost, so they require less intensive cleaning. If they are visibly dirty, you can rinse them in a colander under running water and then dry them with a clean dish towel or paper towels. Avoid submerging cultivated mushrooms completely in water, as this can cause them to become waterlogged.
Mushrooms with exposed gills
Mushrooms with exposed gills, such as oyster mushrooms, portobellos, and shiitakes, are more absorbent than other types of mushrooms. It is best to clean these mushrooms by brushing away dirt with a paper towel, pastry brush, or mushroom brush.
Mushrooms without exposed gills
Mushrooms without exposed gills, such as button mushrooms, creminis, and porcinis, can be rinsed in a colander under running water and then dried with a clean dish towel or paper towels.
Searing or grilling mushrooms
If you are planning to sear or grill mushrooms, it is best to avoid adding extra moisture. In this case, you may want to wipe the mushrooms with a damp paper towel or brush them lightly to remove any dirt.
Cooking mushrooms whole
If you are cooking mushrooms whole, it is generally safe to rinse them quickly and then dry them thoroughly before cooking. This will ensure that any dirt or debris is removed.
In summary, the decision of when to wash mushrooms depends on the type of mushroom, the cooking method, and personal preference. Some people prefer to avoid washing mushrooms altogether, while others find it necessary to remove dirt and debris. It is important to cook mushrooms immediately after washing to prevent discoloration and to ensure optimal texture and flavor.

The myth of mushrooms as sponges
Mushrooms have long been likened to sponges, with many believing that they absorb water when washed and become too soggy to cook. However, this is a myth. While mushrooms do contain a lot of water—more than you'd expect by looking at them—they do not absorb a significant amount when rinsed. In fact, they lose little to no flavour from a quick wash.
The belief that mushrooms are like sponges may stem from their delicate nature and unique growing conditions. Wild mushrooms, for example, are often harvested from unsterile environments with leaves, twigs, pine needles, dirt, and even insects that can cling to the fungi. Cultivated mushrooms, on the other hand, are grown in highly sterile environments, but still require proper cleaning to remove any compost or dirt.
The key to successfully washing mushrooms is to do so just before cooking and to avoid submerging them completely in water. A quick rinse or swish in cold water, followed by drying on a clean towel, is usually sufficient. For mushrooms with exposed gills, such as oyster mushrooms, portobellos, and shiitakes, a dry brush or paper towel can be used to gently remove dirt without adding extra moisture.
It's worth noting that some varieties of mushrooms, such as chanterelles and morels, are more prone to becoming waterlogged and mushy, so a quick rinse and thorough drying are especially important for these types. Additionally, it's generally recommended to wash mushrooms before slicing or cutting them, as exposing their flesh can make them more absorbent.
In conclusion, while mushrooms may have a sponge-like appearance and grow in conditions that require thorough cleaning, they do not behave like sponges when washed. With proper rinsing and drying techniques, any concerns about sogginess or flavour dilution can be easily avoided. So, the next time you're preparing mushrooms, don't be afraid to give them a quick wash to ensure they're clean and ready for your culinary creations.

How to dry mushrooms
While some sources suggest that mushrooms should not be rinsed with water, others recommend giving them a quick rinse and a thorough dry. The right cleaning method depends on the type of mushroom.
For wild mushrooms, like chanterelles or black trumpets, a quick rinse under the faucet is recommended. These mushrooms are often full of bugs, wood chips, and pine needles, so a quick swish in lukewarm water, followed by a drain in a colander, and an immediate blot with a towel should do the trick.
For cultivated mushrooms, like buttons and portobellos, a dry cloth or paper towel can be used to wipe off any dirt or compost. These mushrooms are grown in a sterile environment, so a simple brush or wipe is usually sufficient.
For morels, their honeycomb texture requires a slightly different approach. First, give them a good shake in a paper bag to loosen any dirt or debris. Then, use a mushroom brush to gently brush off any remaining dirt. If you want to keep them whole, you can then wash them by swooshing them in a bowl of water and drying them in a salad spinner.
It's important to note that washing mushrooms can make them soggy, so it's best to cook them right away after rinsing. Additionally, make sure they are fully dry before cooking to avoid a diluted flavor and rubbery, slimy texture.
