Sanitizing Dry Mushrooms: A Step-By-Step Guide

how to sanitize dry mushrooms

Mushrooms are a versatile ingredient, but they can be a little tricky to clean. The cleaning method depends on the type of mushroom and how you intend to use them. Wild mushrooms, for example, may need to be cleaned and dried in the woods, which can be a painstaking process. Cultivated mushrooms, on the other hand, are grown in sterile environments and may only need a quick rinse or brush before use. Regardless of the type of mushroom, it's important to remove any dirt, grit, or bugs to ensure they are safe to consume and don't affect the flavour or texture of your dish.

Cleaning wild vs. cultivated mushrooms

When it comes to cleaning wild vs. cultivated mushrooms, it's important to understand the differences in their growing environments and how these impact the cleaning process.

Wild mushrooms are foraged from natural environments like forests, yards, or roadsides. These environments are unsterile and can host leaves, twigs, pine needles, dirt, and even bugs. Wild mushrooms, such as chanterelles, can be either pristine or covered in debris from the forest floor. Therefore, they require a more thorough cleaning process. It is recommended to check for tiny bug holes at the stem ends. If present, add salt to a bowl of water (1 tablespoon per 4 cups of water), swirl to dissolve, and then soak the mushrooms for 20 minutes before draining and repeating. This process ensures that any tiny creatures are removed. After soaking, wild mushrooms should be dried on a double layer of cotton dish towels.

Cultivated mushrooms, on the other hand, are grown in sterile environments that resemble science laboratories. They are produced using sterilized compost, white coats, and sterile gloves. As a result, cultivated mushrooms are generally cleaner and require a simpler cleaning process. A general rule for cultivated mushrooms purchased from grocery stores is to wash them with water. However, if the mushrooms are relatively clean, simply brushing off the dirt or cutting off any dirty sections, such as the base of the stem, may be sufficient. Cultivated mushrooms are more delicate than wild mushrooms, so it's important to avoid soaking them for extended periods to prevent sogginess.

It's worth noting that some sources suggest that the decision to wash or brush mushrooms depends on personal preference and the intended use. Brushing can effectively remove loose dirt, but water may be necessary to dislodge dirt from crevices and gills. Additionally, certain wild mushrooms, like morels, may require a combination of brushing and washing due to their honeycomb shape, which can trap dirt.

When cleaning wild mushrooms, it is crucial to prioritize safety. Extreme caution is essential when picking and consuming wild mushrooms, and professional guidance or expertise is highly recommended.

Brushing vs. washing

When it comes to cleaning mushrooms, there are two popular methods: brushing and washing. Both methods aim to remove dirt and debris from the mushrooms, but they differ in their approach and suitability for different types of mushrooms.

Brushing Mushrooms

Brushing mushrooms involves using a mushroom brush or a soft-bristled brush, such as an extra-soft toothbrush or a baby brush, to gently remove dirt and debris from the surface of the mushrooms. Brushing is particularly suitable for wild mushrooms, foraged mushrooms, or expensive varieties as it helps prevent damage to the product. It is also effective for removing loose dirt from store-bought mushrooms, which are typically grown on sterile manure. However, brushing may not be as thorough as washing, especially for firmly attached dirt or debris hiding in the gills.

Washing Mushrooms

Washing mushrooms involves submerging them in a large bowl of cold water for a brief period, swirling them around to loosen and remove dirt, and then patting them dry with a clean, lint-free towel. Washing is suitable for most mushrooms, including wild mushrooms and store-bought varieties like white buttons, cremini, and portobello mushrooms. It is important to avoid soaking mushrooms for too long, as they can absorb water, which may affect their texture and cooking characteristics. Washing is generally safe and effective, contrary to some beliefs, as mushrooms are mostly water and can lose moisture during cooking.

The decision between brushing and washing mushrooms ultimately depends on the type of mushrooms, personal preference, and the intended use. Both methods can effectively clean mushrooms when applied appropriately, ensuring they are safe to consume and free from grit.

Using water to wash mushrooms

Mushrooms can be washed with water, contrary to some beliefs. However, it is important to do so correctly to avoid waterlogging the mushrooms, which can affect their texture and taste.

Preparing the Mushrooms

Before washing, cut the mushrooms into pieces. If the mushrooms are very dirty, you can first brush them with a mushroom brush or a soft-bristled toothbrush. If you are washing morels, shake them in a paper bag to loosen any dirt or debris.

Washing the Mushrooms

Fill a large bowl with cold water. Add a few mushrooms at a time, so they are easily manageable. Dunk or swirl the mushrooms in the water for around 10 seconds. You can also add salt to the water, swirling to dissolve it before adding the mushrooms and soaking for 20 minutes. For very dirty mushrooms, you may need to repeat this step.

Drying the Mushrooms

Remove the mushrooms from the water and immediately pat them dry with a clean, lint-free towel. Lay the mushrooms out, caps up, to air-dry. If any dirt remains, use a damp paper towel to wipe it off. Ensure the mushrooms are thoroughly dried before cooking or storing.

Removing stubborn dirt

Once you have your mushrooms, the next step is to inspect them for stubborn dirt or debris. If you spot some stubborn bits, use a damp paper towel or a soft mushroom brush to wipe each mushroom individually. You can also use a clean kitchen towel or a lint-free towel to pat them dry. Extra-soft toothbrushes and baby brushes are gentle and effective for removing dirt from mushrooms.

For more stubborn dirt, you may need to use a paring knife to gently scrape away the first layer of flesh that has dirt or debris attached. This technique is especially useful for mushrooms with dirt embedded in their flesh, which can be challenging to remove with a brush. Cut away any discoloured or soft sections of the mushroom and never consume anything you're unsure about.

If you're dealing with a large number of mushrooms, try using a colander. Place the mushrooms in the colander and spray them with cool water at fairly firm pressure. This will help loosen dirt and debris, which will drain to the bottom of the colander. Then, take each mushroom and spray into the ridges and crevices to remove any remaining dirt.

Finally, always ensure your mushrooms are thoroughly dried before cooking or storing them. Pat them dry with a kitchen towel or use a salad spinner to remove excess moisture. Remember, mushrooms are like little sponges, so it's important to avoid soaking them in water for too long to prevent them from becoming waterlogged, which can affect their cooking properties and texture.

Drying methods

For Wild Mushrooms

Wild mushrooms, foraged from the woods or purchased from a farmer's market, often require more thorough cleaning due to their unsterile growing environment. Here are some steps to sanitize and dry wild mushrooms:

  • Use a brush to gently remove loose dirt, debris, and grit from the mushroom's surface. You can use a mushroom brush, a dry pastry brush, or even a soft-bristled toothbrush.
  • If the mushrooms are heavily soiled, you can rinse them briefly in cold water. Fill a large bowl with water, add a few mushrooms at a time, and swirl them gently for a few seconds. Then, transfer them to a clean towel and pat them dry.
  • To remove stubborn dirt or bugs, use a damp paper towel to wipe the mushrooms clean. Alternatively, use a paring knife to carefully remove any crusty dirt clods.
  • To prevent moisture buildup, consider using a mesh bag or hanging rack to allow for airflow and initial moisture loss.
  • For more extensive drying, a dehydrator can be used. Place the cleaned mushrooms in the dehydrator trays and run the machine for several hours or overnight until the mushrooms are completely dry.

For Cultivated Mushrooms

Cultivated mushrooms, purchased from grocery stores, are typically grown in sterile environments and may require less intensive cleaning. Here are some steps to sanitize and dry cultivated mushrooms:

  • Brush off any visible dirt or debris from the mushroom's surface using a dry towel or a mushroom brush.
  • If the mushrooms appear clean after brushing, they are likely ready for use and do not require washing.
  • If there are still some light soiled spots, you can rinse the mushrooms briefly under running water, gently rubbing the dirty spots with your fingers.
  • After rinsing, pat the mushrooms dry with paper towels or clean kitchen towels.
  • Cultivated mushrooms are not typically dried using dehydrators but can be air-dried by placing them on a clean surface or hanging them in a well-ventilated area.

It is important to note that the specific drying method may vary depending on the type of mushroom and personal preferences. Some mushrooms, like morels and chanterelles, may have unique cleaning and drying requirements. Always ensure that your mushrooms are thoroughly cleaned and sanitized before consuming them.

Frequently asked questions

If your mushrooms are visibly dirty, use a dry pastry brush or a mushroom brush to gently rub off any dusty or muddy bits. If there are crusty dirt clods, use a paring knife to remove them. If they still seem dirty, moisten a paper towel slightly and wipe them down. If you are sautéing, baking, or roasting the mushrooms, you can be more liberal with the water.

If you plan to eat the mushrooms raw, keep them as dry as possible. Avoid running water over them unless absolutely necessary. If they are visibly dirty, use a dry brush or paper towel to clean them.

Wild mushrooms are more likely to be dirty than cultivated mushrooms. Before placing them in your bag, brush off bolete caps and slice away all the dirt on the stems. Tap the char off your burn morels and cut the dirt off the bottom of the stems. Use a bag with a mesh bottom so dirt and debris can fall through.

If you have a large number of mushrooms to sanitize, you can use a dehydrator. If you are outdoors, you can use a mesh hanging rack to allow the mushrooms to lose some moisture before using a dehydrator.

Most pre-sliced mushrooms are already cleaned and ready to eat. If you see some dirt, give them a shake in a colander to loosen it, then give them a quick rinse before cooking. Dry them off with paper towels or a clean kitchen towel.
