Washing Mushrooms: To Rinse Or Not Before Drying?

There are various ways to clean mushrooms, and the method you choose will depend on your personal preference and the type of mushroom. Wild mushrooms, for example, may need more trimming than commercially grown mushrooms, and some types of wild mushrooms may have dirt attached to the base of the stem that doesn't brush off easily. Cultivated mushrooms, on the other hand, are grown in sterile environments and may only need to be brushed off with a dry towel or mushroom brush. While some sources advise against rinsing mushrooms with water, others argue that a quick rinse or dunk is enough, as mushrooms are mostly water, so a little more won't change their flavour or texture. So, do you need to rinse the dirt off the stems of mushrooms before drying them? The answer may depend on the type of mushroom and your personal preference.

The pros and cons of rinsing mushrooms

There are differing opinions on whether mushrooms should be rinsed with water. While some believe that rinsing mushrooms is essential to remove dirt and other debris, others argue that it can lead to sogginess and affect the texture and flavour. Here are some pros and cons of rinsing mushrooms:

Pros of Rinsing Mushrooms:

• Rinsing mushrooms with water can effectively remove dirt, debris, and potential bugs, especially when combined with a brush or paper towel.
• It is a quick and easy method to clean mushrooms, especially when they are very dirty.
• Culinary specialists like Alton Brown and Harold McGee have supported the idea of rinsing mushrooms, claiming that the weight change due to water absorption is minimal and not an issue.
• Rinsing can be particularly useful for certain mushroom varieties, such as morels, chanterelles, and foraged mushrooms, which tend to be very dirty or bug-infested.

Cons of Rinsing Mushrooms:

• One of the main concerns with rinsing mushrooms is the belief that they will absorb too much water, leading to sogginess and a rubbery or slimy texture. This can affect the cooking process and the final dish's texture and flavour.
• Mushrooms that have been rinsed may not brown nicely when cooked, which is undesirable for certain recipes.
• Rinsing mushrooms can be seen as unnecessary if they are store-bought and not visibly dirty. A light brushing or wiping with a damp paper towel may be sufficient in these cases.
• Rinsing mushrooms before storing them is not recommended as unwashed mushrooms tend to last longer in the refrigerator.

How to rinse mushrooms

There are several methods to rinse mushrooms, and the best one for you will depend on the type of mushroom and your personal preference. Here is a step-by-step guide on how to rinse different types of mushrooms:

White, button, cremini, and shiitake mushrooms:

• These mushrooms are usually clean, so a damp paper towel or a soft mushroom brush to wipe each mushroom may suffice.
• If they are dirty, place them in a colander and give them a quick rinse with cold water.
• Shake off the excess water and dry them with a paper or kitchen towel.

Portobello mushrooms:

• Remove the stems, which can be saved for stuffing or broth.
• Use a spoon to gently scrape off the gills from the underside of the cap.
• Place the mushrooms in a colander and give them a quick rinse.
• Dry them with a paper or kitchen towel.

Morel mushrooms:

• These mushrooms can be very dirty, so it is best to use a brush and some water to clean them.
• You can also soak them in salted water to kill any bugs and remove dirt.
• After soaking, give them a quick rinse and pat them dry with a paper towel.

Chanterelle mushrooms:

• Check for tiny bug holes at the stem end.
• If there are no bug holes, rinse the mushrooms with cold water.
• If there are bug holes, add salt to the water (1 tablespoon per 4 cups of water).
• Soak the mushrooms for 20 minutes, drain, and repeat.
• Dry the mushrooms on a double layer of cotton dish towels.

Wild mushrooms:

• Wild mushrooms will likely need more trimming than commercially grown mushrooms.
• Use a knife to trim off any stubborn clumps of dirt and inedible stems.
• Place the mushrooms in a colander and give them a quick rinse with cold water.
• Shake off the excess water and dry them with a paper or kitchen towel.

Sliced mushrooms:

• Give them a shake in a colander to loosen any dirt.
• Rinse them quickly just before cooking and dry them with a paper or kitchen towel.

It is important to note that mushrooms should be cleaned just before cooking, as unwashed mushrooms last longer in the refrigerator. Additionally, while some people believe that washing mushrooms will make them soggy, others argue that a quick rinse is sufficient and will not affect the texture or flavor.

How to dry mushrooms

Drying mushrooms is a straightforward process, but it does require several steps to ensure the mushrooms are clean and dry. Here is a guide on how to dry mushrooms:

Step 1: Clean the Mushrooms

Mushrooms often have dirt or other debris on them, so it is important to clean them before drying. There are several ways to do this:

• Use a damp paper towel or a soft mushroom brush to wipe each mushroom individually. This method is time-consuming but effective.
• If the mushrooms are not too dirty, a light brushing with a clean kitchen towel may be sufficient.
• For very dirty mushrooms, such as morels, it is recommended to use a scrub brush and some water to get them clean.
• For sliced or wild mushrooms, place them in a colander and shake them lightly to loosen any dirt, then give them a quick rinse with cold water.
• If there is stubborn dirt on the stems, use a knife to carefully scrape or trim it off.

Step 2: Dry the Mushrooms

Once the mushrooms are clean, it is important to dry them thoroughly before storing or using them. Here are some methods for drying mushrooms:

• Use paper towels or a clean kitchen towel to pat the mushrooms dry.
• Place the mushrooms in a well-ventilated area and leave them to air dry for about a week. They should be dry enough when they make a sound when flicked.
• Use a salad spinner to dry the mushrooms, especially if they have been soaked or rinsed.
• If you plan to use the mushrooms for cooking, make sure they are as dry as possible before cooking to avoid sogginess.

Step 3: Store the Dried Mushrooms

Once the mushrooms are completely dry, you can store them in an airtight container or bag. Dried mushrooms can last for a long time if stored properly, but it is best to use them within a year for the best quality.

Step 4: Optional - Dehydrate the Mushrooms

If you want to extend the shelf life of the mushrooms even further, you can use a dehydrator to remove any remaining moisture. However, this may affect the potency and efficacy of the mushrooms over time.

By following these steps, you can effectively dry mushrooms and preserve them for future use.

The best way to clean wild mushrooms

There are several ways to clean wild mushrooms, and the best method may depend on the type of mushroom and the amount of dirt. Here is a step-by-step guide to cleaning wild mushrooms:

Step 1: Initial Cleaning

Before bringing your mushrooms home, it is important to remove any parts that are too dirty or woody, especially the base where the mushroom was attached to the ground or wood. You can also trim any orange parts, as this colouration indicates old age.

Step 2: Break Down

Break the mushrooms into smaller sections or chunks to expose the interior and make cleaning easier. This step is especially important for larger mushrooms.

Step 3: Choose Your Cleaning Method

Option 1: Damp Cloth or Brush

Using a damp paper towel, soft mushroom brush, or even a clean kitchen towel, wipe each mushroom individually to remove dirt. This method is gentle and effective for most types of mushrooms, but it can be time-consuming for a large batch.

Option 2: Bowl or Colander Rinse

If your mushrooms are very dirty, you may need to use water for a deeper clean. Place the mushroom chunks in a large bowl or colander and rinse them with cold water. You can agitate the mushrooms with your hands or use a spray setting on your faucet to target dirt from different angles. For extra dirty mushrooms, you can soak them in saltwater to kill bugs and remove stubborn dirt.

Option 3: Combination Method

For very dirty mushrooms, you may want to combine the damp cloth method with the bowl or colander rinse. After breaking the mushrooms into sections, use a damp towel to check for and remove bugs, dirt, larvae, and other debris. Then, plunge the sections into a bowl of water or rinse them in a colander to ensure they are thoroughly cleaned.

Step 4: Dry Thoroughly

Regardless of the cleaning method chosen, it is crucial to dry your mushrooms thoroughly. Pat the mushrooms firmly with kitchen towels or use a salad spinner to remove excess moisture. Allow the mushrooms to air dry for at least 24 hours, or until completely dry, before cooking or storing.

Additional Tips:

• Clean your mushrooms immediately after picking to prevent dirt from spreading to other mushrooms in your collection.
• Always clean mushrooms just before cooking, as rinsing can reduce their shelf life if they are not dried properly before storage.
• Avoid soaking mushrooms for extended periods, as they can absorb a small amount of water, potentially affecting their texture and browning capability during cooking.
• If you plan to freeze your mushrooms, ensure they are as dry as possible to prevent sogginess.

By following these steps and tips, you can effectively clean wild mushrooms and ensure they are safe and ready for cooking or storage.

The best way to clean cultivated mushrooms

There are several ways to clean cultivated mushrooms, and the best method will depend on the type of mushroom and the amount of dirt present. Here is a step-by-step guide to cleaning cultivated mushrooms:

Step 1: Remove any large clumps of dirt

Use a small brush, a damp paper towel, or a soft mushroom brush to wipe each mushroom gently and remove any visible dirt. If the mushrooms are store-bought and not very dirty, this step may be sufficient, and no further cleaning is needed.

Step 2: Rinse with cold water

If the mushrooms are still dirty, the next step is to rinse them with cold water. Place the mushrooms in a colander and give them a quick rinse, or use a bowl of cold water to swish them around gently. Avoid soaking the mushrooms for an extended period, as they can absorb water and become soggy.

Step 3: Remove stems and trim

Remove the stems of the mushrooms, which can be saved for later use in stuffing or broths. Trim off any damaged or bruised sections of the mushroom caps and remove any tough stems. For morel mushrooms, it is recommended to halve them lengthwise before rinsing in water.

Step 4: Use salted water (optional)

If the mushrooms are very dirty or likely to have bugs, you can soak them in lightly salted water for a few minutes. This will help kill any insects and remove stubborn dirt. However, this step is optional and may not be necessary for all types of mushrooms.

Step 5: Dry the mushrooms

After rinsing, it is important to dry the mushrooms thoroughly. Use paper towels or clean kitchen towels to pat them dry. Make sure to remove as much moisture as possible, especially if you plan to freeze the mushrooms.

Step 6: Store or cook

Once the mushrooms are clean and dry, they are ready to be cooked or stored. Cleaned mushrooms can be stored in the refrigerator for a few days, but it is best to cook and consume them as soon as possible to ensure freshness and avoid slime development.

In summary, the best way to clean cultivated mushrooms is to first remove large dirt clumps, then give them a quick rinse with cold water, trim the stems and remove any damaged parts, optionally soak in salted water, thoroughly dry them, and finally, cook or store them. Remember to always inspect your mushrooms and adjust the cleaning method as needed.
