Cleaning wild mushrooms before cooking

Firstly, when foraging wild mushrooms, it is advisable to clean them immediately after picking. This helps prevent dirt from spreading to other mushrooms in your basket. Use a brush or a sharp knife to remove any visible dirt, clay, or debris from the mushrooms before placing them in a clean, sturdy-sided container. You can also cut them above the dirt line and give them a few taps against the ground to dislodge any bugs, dirt, or sticks.

Once you're back home, give the mushrooms a quick rinse if you like, although some sources advise against soaking them as they may become waterlogged. You can also use a damp towel or paper towel to gently brush away any remaining dirt or debris from the exterior of the mushrooms. Be sure to inspect the crevices and lobes for any larvae or bugs. Cut away any embedded needles, sticks, or other foreign objects, as well as any orange parts, as this colour indicates that the mushroom is old.

For more mature mushrooms, consider scraping or peeling away the "teeth" on the underside of the cap, as these can be bitter. You can also use a paring knife to gently remove any stubborn or embedded pieces of dirt. If you're concerned about parasites, you may want to briefly soak the mushrooms in a water bath, although this is not the preferred method for all types of mushrooms.

Finally, be sure to trim the dirty or sandy base of the mushroom stem before cooking. This is usually the part that was attached to the tree or the ground, and it tends to be the dirtiest.

Remember, always properly identify wild mushrooms before consuming them, as some varieties may be unsafe for consumption.

Using water to rinse wild mushrooms

Wild mushrooms are often harvested from unsterile environments, such as the side of a tree, and can host leaves, twigs, pine needles, dirt, and bugs. Therefore, it is important to clean them before cooking.

There are two schools of thought when it comes to cleaning mushrooms: using water to rinse or soak them, or simply brushing off any dirt. The latter is a good option if the mushrooms are relatively clean and the dirt is loose. However, if there is more stubborn dirt or it is hiding in the gills, then water may be necessary.

If you choose to use water, fill a large bowl with cold water and add a couple of tablespoons of salt. Add a few mushrooms at a time, swirling them around in the water to loosen any dirt and bugs. You can also submerge them and agitate the water to move them around. If the mushrooms are very dirty, you may need to soak them for a short period, changing the water as needed until the dirt is removed.

After rinsing or soaking, it is important to dry the mushrooms thoroughly. Lay them on a clean kitchen towel or paper towel and pat them dry. Make sure to clean mushrooms just before cooking, as they don't store well when wet.

Trimming and inspecting wild mushrooms

Firstly, it is advisable to clean wild mushrooms as soon as they are harvested to reduce the amount of dirt brought home. This involves giving them a quick brush with a hand or a mushroom brush and cutting off the dirty base where the mushroom was attached to the ground, removing any sections with discolouration or softness. It is important to use your best judgement and never eat anything you are unsure about.

When inspecting wild mushrooms, it is crucial to break them vertically into smaller chunks to expose the interior. This allows for the removal of any larger debris, such as sticks or leaves, which may be embedded within the mushroom. A paring knife can be useful for digging out or cutting off stubborn debris.

Before rinsing with water, it is recommended to cut off the end of the stem, which often contains the most dirt and debris. This step also creates a flat base for the mushroom, making slicing easier and safer. If the mushroom is mature, consider scraping or cutting away the "teeth" on the underside, as they may have a bitter flavour.

When rinsing wild mushrooms, it is best to do so just before cooking, as rinsing can reduce their shelf life. Rinsing under cold running water is recommended, and a spray nozzle can help dislodge stubborn debris. A colander can also be used to swirl the mushrooms gently and encourage the dirt to fall away.

After rinsing, it is important to dry the mushrooms thoroughly. This can be done by patting them with a clean kitchen towel or paper towel to remove any excess moisture.

Remember, there is no one-size-fits-all approach to trimming and inspecting wild mushrooms, and the specific method may vary depending on the species. Always exercise caution and avoid consuming anything you are uncertain about.

Cleaning wild mushrooms in the forest

Wild mushrooms are mushrooms harvested in the wild, often found growing on the side of a tree, at the base of a tree, or in your driveway or yard. They are usually harvested in unsterile environments, which can host dirt, clay, sand, pine needles, leaves, twigs, and bugs.

When cleaning wild mushrooms in the forest, it is important to bring the right tools to help keep the dirt where it belongs and not in your meal. Bring a sharp knife to cut the mushroom from the ground, a brush to wipe away any debris, and a sturdy-sided container to carry the mushrooms in. Before placing the mushrooms in your container, cut the dirty base off and give it a quick clean with a brush or blow on it to remove debris. If the mushroom is very dirty, it might be best to leave it behind.

Once you have returned from the forest, you can begin to prepare the mushrooms for cooking. If you did not clean and trim the mushrooms in the forest, you will need to do this now. Use a small knife to trim any debris or inedible parts, such as discoloured or soft sections. Then, gently brush the mushroom with a pastry brush. If there is still dirt remaining, rinse the mushrooms under cold water. Avoid soaking the mushrooms, as they will absorb a lot of water and become soggy. If the mushrooms are very wet, lay them out on sheet pans with paper towels and place them in the refrigerator overnight to remove the moisture.

If the mushrooms are very dirty, you may need to soak them in water to remove the dirt. Fill a large bowl or your sink with cold water and place the mushrooms in the water, swishing them around with your hand. The dirt will fall to the bottom, and you can remove the clean mushrooms from the middle. Repeat this process with fresh water until the mushrooms are clean. Then, place the mushrooms in a colander and spray them with cool water on fairly firm pressure from multiple angles to encourage the dirt to drain to the bottom.

Drying wild mushrooms after rinsing

Drying wild mushrooms is a great way to preserve them for long-term storage. Here are some detailed, step-by-step instructions on how to dry wild mushrooms after rinsing:

Preparing the Mushrooms

Before drying, it is important to clean the mushrooms thoroughly. Use a damp paper towel or a brush to wipe away any visible dirt, debris, or needles. Remove the dirty/woody base where the mushroom was attached to the ground, and inspect for any discolouration, soft spots, or worm holes. Cut away any sections that appear suspect. For mushrooms with a lot of crevices, a quick rinse under running water may be necessary to remove hidden grit, but make sure they dry properly before proceeding.

Air-Drying

Place the cleaned mushrooms in a container that allows for good airflow, such as a mesh colander or a baking rack set on a baking sheet. Do not overcrowd the mushrooms. Leave them in a well-ventilated area, preferably with access to sunlight. The drying time will vary depending on humidity levels and the size of the mushrooms, but it typically takes about 7-10 days for the mushrooms to fully dry.

Oven-Drying

To expedite the drying process, you can partially dehydrate the mushrooms in an oven. Preheat the oven to 175°F/80°C. Place the mushrooms on an oven-proof plate or a baking rack over a sheet pan. Leave the oven door slightly ajar to allow moisture to escape. Cook for 1-2 hours, flipping them halfway through. After this, the mushrooms will be partially dried.

Finishing and Storage

Once the mushrooms are partially dried, transfer them back to a colander to continue air-drying for another 3-5 days until they are completely dry. You can also finish them off in a food dehydrator. After they are fully dried, store the mushrooms in an airtight container in a cool, dark place. Properly dried mushrooms can last for years when stored correctly.

Drying wild mushrooms is a simple process that requires patience and attention. By following these steps, you can effectively dry your wild mushrooms and enjoy their flavour and nutritional benefits for a long time.
