The Best Way To Clean Cremini Mushrooms

Cremini mushrooms are a type of cultivated mushroom, typically purchased from grocery stores. They are grown in sterile environments, and therefore do not need extensive washing. To clean them, use a brush to gently remove any visible dirt, or cut off the dirty end of the stem. If the mushrooms are very dirty, you can rinse them under running water, but this should be avoided if possible, as it can make the mushrooms soggy and unpleasant. After cleaning, the mushrooms can be sliced and cooked as desired.

Cleaning cultivated vs. wild mushrooms

When it comes to cleaning mushrooms, the first step is to determine whether they are cultivated or wild. Cultivated mushrooms, which are typically found in grocery stores, are grown in sterile environments resembling science laboratories. On the other hand, wild mushrooms are foraged or harvested from natural environments like forests, yards, or driveways. These different growing conditions result in varying levels of cleanliness and require distinct cleaning approaches.

Cleaning Cultivated Mushrooms

Cultivated mushrooms, owing to their sterile cultivation conditions, are generally cleaner and require less intensive cleaning methods. Here are some steps to clean cultivated mushrooms:

• Inspect the mushrooms for dirt or debris.
• If the mushrooms appear relatively clean, use a dry towel or a mushroom brush to gently brush off any visible dirt.
• If necessary, cut off the dirty end of the stem or any sections holding dirt.
• For store-bought mushrooms with a strong peaty smell or clinging growing medium, gently rinse them under running water.
• Pat the mushrooms dry with a paper towel or kitchen towel.

Cleaning Wild Mushrooms

Wild mushrooms, foraged from natural environments, often harbour more dirt, grit, and even tiny insects. They require more thorough cleaning. Here are some general steps for cleaning wild mushrooms:

• Identify the type of wild mushroom you have, as different varieties may have unique cleaning requirements. Common wild mushrooms include Morel, Hen of the Woods, Chicken of the Woods, and Puffballs.
• Inspect the mushrooms for dirt, grit, or bug holes, especially at the stem end.
• If the mushrooms are pristine or only lightly soiled, brush off the dirt with a mushroom brush or a dry towel.
• If the mushrooms are heavily soiled, cut them into pieces before washing.
• Submerge the mushroom pieces in water and agitate them to remove dirt and grit.
• For mushrooms with bug holes, add salt to the washing water (1 tablespoon per 4 cups of water). Soak the mushrooms for 20 minutes, then drain and repeat the process.
• Pat the mushrooms dry with a cotton dish towel or kitchen towel.

It's important to note that some sources suggest that cultivated mushrooms should not be washed due to their sterile growing conditions. However, others argue that a gentle rinse under running water is acceptable and will not significantly affect the mushrooms' flavour or texture. Always handle mushrooms gently, especially cultivated varieties, as their caps can be delicate and prone to breaking.

How to clean without water

How to Clean Cremini Mushrooms Without Water

Cremini mushrooms are cultivated mushrooms that are typically commercially raised and sold in grocery stores. They are usually not very dirty and can be cleaned without water. Here are some ways to do this:

Brush Off Dirt

Use a dry towel, a mushroom brush, or a pastry brush to gently brush off any visible dirt from the surface of the mushroom caps. You can also use a clean, dry toothbrush for this purpose. Make sure to clean the gills and the rim beneath the cap as well, as this is where most of the bacteria on mushrooms live. If the dirt is stubborn, you can cut it off with a knife or paring knife.

Wipe with a Damp Paper Towel

If the mushrooms still seem dirty, you can use a slightly damp paper towel or a clean kitchen towel to gently wipe each mushroom and remove any remaining dirt. Make sure to pat the mushrooms dry with a paper towel after cleaning.

Trim the Stem

Another way to clean cremini mushrooms is to trim or twist off the stem of each mushroom. This removes any dried-out or dirty sections and creates a flat base for slicing or further preparation. You can reserve the stems to use in stuffed mushroom fillings if desired.

It is important to note that if you are eating the mushrooms raw, it is best to avoid using water unless absolutely necessary. Additionally, clean the mushrooms right before using them, as moisture can cause them to spoil more quickly.

When to use water

Cremini mushrooms are cultivated mushrooms, grown in sterile environments, so they are usually quite clean and do not need to be washed. However, there are certain situations where it is necessary to use water to clean them:

Firstly, if your cremini mushrooms are starting to deteriorate and develop a slime on the outside, it is recommended to give them a quick wash. Fill a bowl with water, swish the mushrooms around to dislodge any debris, and then transfer them to a paper-towel-lined plate to absorb any excess water.

Secondly, if you have a large number of cremini mushrooms to clean, it may be more efficient to use water. In this case, gently running them under the faucet and rubbing any dirty spots with your fingers or a wet paper towel can be a quick and effective method. Again, be sure to dry them on a paper towel after washing.

Thirdly, if your cremini mushrooms are exceptionally dirty with lots of nooks and crannies filled with dirt, you may need to soak them in water to thoroughly clean them. Cut the mushrooms into pieces, submerge them in water, and agitate them to dislodge any dirt. Then, transfer them to a clean kitchen towel to pat dry.

Finally, if you have foraged your cremini mushrooms yourself, they may harbour tiny creatures or bugs. In this case, you can use salty water to evict any unwanted guests. Add one tablespoon of salt to four cups of water, swish to dissolve, and then soak the mushrooms for 20 minutes. Drain and repeat the process with fresh salty water if necessary.

While it is generally recommended to avoid using water to clean cultivated mushrooms like cremini, there are certainly situations where it is beneficial or even necessary. Just be sure to dry the mushrooms thoroughly after washing to prevent sogginess and preserve their flavour and texture.

How to dry mushrooms

Cremini mushrooms, like other cultivated mushrooms, are grown in sterile environments, so they do not need to be washed extensively. To clean them, you can gently wipe them with a damp paper towel, brush off any visible dirt, or rinse them briefly under running water.

Now, if you're interested in drying mushrooms, it's surprisingly simple to do so at home without any specialized equipment. Here's a step-by-step guide on how to dry mushrooms:

• Start with fresh mushrooms that are in good condition.
• Clean the mushrooms by wiping them with a lightly dampened towel. Avoid washing them under running water.
• Place the mushrooms in a container that allows for air circulation, such as a mesh colander or a baking rack over a baking sheet. Ensure they are not overcrowded.
• Set the container in a well-ventilated area, preferably with sunlight.
• Allow the mushrooms to air-dry for 7 to 10 days. The drying time may vary depending on humidity levels and the size of the mushrooms.
• Check if the mushrooms are fully dry by squeezing them gently. They should feel hard and not give at all when squeezed.
• Once completely dry, store the mushrooms in a cool, dry place. They can be stored for up to 2 years or even longer.

Additionally, you can expedite the drying process by partially dehydrating the mushrooms in an oven before finishing the air-drying process. You can also use a dehydrator or an oven to dry mushrooms, although it's not necessary. If you use a dehydrator, set it at the appropriate temperature (around 55°C) for 12 to 24 hours, or until the mushrooms snap cleanly when tested.

Dried mushrooms are commonly used in Asian cooking, adding a "meatiness" to dishes. They intensify the umami flavor and are excellent for stocks, soups, braises, and stir-fries. Remember, drying mushrooms is a great way to preserve them for later use!

Removing bugs from mushrooms

Inspect and Trim:

First, visually inspect the mushrooms for any signs of bugs or larvae. Trim any obviously bitten, discoloured, or damaged areas of the mushroom. Slice across the base of the stem to check for bug holes, which indicate the presence of larvae. If the mushrooms are heavily infested, you may need to discard them or try other removal methods first.

Soaking:

For certain types of mushrooms, such as Morels and Oysters, a short soak in saltwater can help draw out and kill bugs and larvae. Use just a couple of tablespoons of salt per few cups of water, and don't soak for more than 5-10 minutes to avoid affecting the texture. After soaking, let the mushrooms dry before use or storage.

Plastic Bag Isolation:

Place the mushrooms inside a sealable plastic bag, such as a Ziploc bag. Seal all but one small corner of the bag, then use your mouth to suck out as much air as possible before sealing it shut. Put the bag in the refrigerator for 8-10 hours. The lack of oxygen will force any larvae inside the mushrooms to crawl out and cling to the sides of the bag. After the allotted time, dump out the mushrooms and brush off any remaining larvae.

Water Dip and Swish:

For mushrooms like wild oysters, which tend to attract beetles, dip and swish them in clean water. Use your fingers to run across the gills during or after swishing to dislodge any bugs. Then, place the mushrooms gill-side down on a paper towel or paper bag to drain and dry.

Cooking:

Wild mushrooms should always be cooked before eating, as cooking will kill any remaining bugs or larvae that may be present. Cooking also neutralizes any potential toxins or harmful substances that could be present in wild mushrooms.

Remember, it is important to properly identify wild mushrooms before consuming them, as some varieties can be toxic. Always cook wild mushrooms thoroughly and avoid consuming any mushrooms you cannot confidently identify.
