Dried shiitake mushrooms may not need washing

Dried shiitake mushrooms are usually sold as caps, which are very clean. The drying process involves heat, which may pasteurize the caps and remove bacteria. However, dried shiitake mushrooms may still have debris on them. It is recommended to wash all produce items that come into your kitchen, as wild dirt can contain moulds, spores, bacteria, and toxins.

Some people choose to wash their dried shiitake mushrooms before use, especially if they plan to grind them into mushroom powder. One way to clean them is to use a salad spinner or a colander. Place the mushrooms in the spinner or colander and rinse them under cold water for 30-45 seconds. While rinsing, gently move the mushrooms around with your hands to help remove any dirt or debris. Spin dry immediately to eliminate as much liquid as possible.

Another method is to wet a sheet of paper towel or a clean kitchen sponge and gently wipe each mushroom cap, making sure to clean the back as well. Remove any visible dirt or debris hiding under or around the gills. However, some people choose not to wash their dried shiitake mushrooms, especially if they are going to be grinding them into a powder and want to keep them dry.

It is worth noting that mushrooms can absorb a small amount of moisture if washed (around 1-2% by weight), but this may not significantly impact cooking. Ultimately, the decision to wash dried shiitake mushrooms or not is a matter of personal preference, and there are no clear guidelines on whether it is necessary.

Wild shiitake mushrooms should be washed

Wild shiitake mushrooms, in particular, can be especially dirty and may contain wild dirt, moulds, spores, bacteria, and toxins. Therefore, it is essential to wash them thoroughly before use. One effective method is to use a salad spinner, placing the mushrooms in the spinner and rinsing them under cold water for 30-45 seconds. While rinsing, gently move the mushrooms around to help dislodge any dirt or debris. Immediately spin them dry to eliminate excess moisture.

If you do not have a salad spinner, you can use a colander or a damp paper towel. With a colander, give the mushrooms a quick rinse and then wipe each one with a sheet of dry paper towel before letting them air dry. Alternatively, gently wipe each mushroom cap with a damp paper towel, ensuring you turn it around to clean all surfaces, including under and around the gills.

It is worth noting that the stems of shiitake mushrooms are known to be tough and leathery, firmly attached to the caps, and often discarded due to their unpleasant flavour and fibrous texture. However, they are not poisonous, and if you choose to consume them, be sure to clean them thoroughly along with the caps to remove any dirt or debris.

Using a brush or damp paper towel to clean shiitake mushrooms

It is generally recommended to wash or clean any produce before consuming it, and shiitake mushrooms are no exception. While shiitake mushrooms are cultivated in a wood-based substrate and are not as dirty as wild mushrooms, they may still contain traces of fertilisers, pesticides, moulds, spores, bacteria, and toxins.

  • Prepare a damp paper towel: Wet a sheet of paper towel with clean water. Ensure that the paper towel is damp and not dripping wet.
  • Gently wipe each mushroom: Use the damp paper towel to gently wipe the surface of each shiitake mushroom. Turn the mushroom around and clean all sides, including under and around the gills, to ensure that all visible dirt or debris is removed.
  • Dry the mushrooms: After cleaning, place the shiitake mushrooms on a dry surface or use a fresh, dry paper towel to gently pat them dry. Removing excess moisture will help prevent the mushrooms from becoming soggy and ensure they are ready for cooking or further preparation.
  • Remove the stems: Shiitake mushroom stems are known for being tough and fibrous, with an unpleasant flavour. Pinch the stem at the base where it meets the cap and slowly pry it off. You can further slice or quarter the mushrooms for grilling or stir-frying.
  • Storage: Fresh shiitake mushrooms can be stored in the refrigerator for a couple of days. Place them loosely in a container and cover them with a damp paper towel to maintain freshness.

By following these steps, you can effectively clean shiitake mushrooms using a brush or damp paper towel, ensuring that they are free of dirt and debris and ready for cooking or further preparation.
