What You'll Learn

Cut the stems and caps apart
Shimeji mushrooms are a type of edible mushroom with over twenty species. They are defined by their long stems and globular caps and are native to forests in East Asia and some parts of Northern Europe.
To prepare white shimeji mushrooms, start by cutting the base of the mushroom bundle with a sharp kitchen knife. This step removes the part that binds the mushrooms together. After cutting the base, separate the individual mushrooms by pulling them apart with your fingers. You can also use a knife to help you separate the stems and caps, ensuring that you don't damage the mushrooms in the process.
Once you have separated the stems and caps, give the mushrooms a quick rinse under cold running water if they appear dirty. Be careful not to soak the mushrooms, as they will absorb water and become mushy. Instead, gently brush off any dirt or rinse them briefly and pat them dry with a paper towel.
Now that the stems and caps are apart and cleaned, you can choose to cook them as they are or cut them further to your desired size. Both the stems and caps are edible, but some cooks prefer to use only the caps. You can cook the mushrooms in various ways, including sautéing, stir-frying, boiling, or slow-roasting them.

Wash and dry the mushrooms
To prepare white shimeji mushrooms, it is important to wash and dry them thoroughly before cooking. Firstly, inspect the mushrooms for any dirt. If they appear dirty, gently rinse them under cold running water, taking care not to scrub too hard as they may be damaged. You can also use a brush to gently remove any dirt. After rinsing, use a paper towel to pat them dry. Alternatively, you can let them air dry on a clean surface before cooking.
It is worth noting that there is a common misconception that mushrooms should not be washed. However, this is simply a myth. A quick rinse will not cause any harm, as long as you avoid soaking them for an extended period, as they will absorb too much water.
When washing mushrooms, it is important to examine them for any signs of spoilage. Mushrooms should have a plump texture, uniform colour, and pleasant smell. Avoid mushrooms that have dark or mouldy spots, or smell funky, like ammonia or fish.
Proper storage is crucial to maintain the freshness of unwashed mushrooms. They should be stored in a loose paper bag in the refrigerator, which allows them to breathe. Placing the paper bag inside a plastic bag can help prevent the mushrooms from absorbing odours from the fridge.
By following these steps, you can effectively wash, dry, and store white shimeji mushrooms, ensuring they are clean, fresh, and ready for cooking.
