Pre-wash preparation: Rinse mushrooms gently under cold water to remove dirt and debris
A slightly fishy smell on mushrooms can be off-putting, but before reaching for strong cleansers or discarding them entirely, consider the power of a gentle rinse. This simple pre-wash preparation step is often overlooked, yet it plays a crucial role in addressing unwanted odors and ensuring your mushrooms are safe and enjoyable to eat.
Rinsing mushrooms under cold water serves a dual purpose: it removes surface dirt and debris, and it can help mitigate mild off-flavors. The key lies in the gentle approach. Unlike sturdy vegetables, mushrooms are delicate and porous, absorbing water quickly. A forceful spray or prolonged soaking can lead to waterlogged mushrooms, diluting their flavor and altering their texture.
The technique is straightforward: hold the mushrooms under a steady stream of cold water, using your fingers to lightly rub away any visible dirt. For clustered mushrooms like shiitakes or oysters, separate the caps to ensure thorough cleaning. Avoid using soap or detergents, as their residue can be difficult to remove and may affect the taste. This method is particularly effective for addressing a slight fishy smell, which is often caused by naturally occurring compounds like trimethylamine. Cold water helps to rinse away these compounds without damaging the mushroom's structure.
While rinsing is a vital step, it's not a cure-all. If the fishy odor persists after cleaning, it may indicate spoilage, especially if accompanied by sliminess or discoloration. In such cases, it's best to discard the mushrooms. However, for fresh mushrooms with a mild odor, a gentle rinse can make a significant difference. This method is especially useful for wild mushrooms, which are more prone to carrying debris and earthy flavors.
In summary, a gentle rinse under cold water is an essential pre-wash preparation step for mushrooms with a slight fishy smell. It effectively removes dirt and can reduce unwanted odors without compromising the mushroom's quality. By mastering this simple technique, you can ensure your mushrooms are clean, safe, and ready to enhance your culinary creations. Remember, the key is gentleness—a light touch goes a long way in preserving the delicate nature of mushrooms.

Vinegar solution: Soak in water with a splash of vinegar to neutralize odors
A slightly fishy smell on mushrooms can be off-putting, but it’s often a sign of mild spoilage or improper storage. Vinegar, a natural deodorizer, can help neutralize these odors due to its acidic properties, which break down the compounds causing the smell. This method is simple, cost-effective, and avoids harsh chemicals, making it a go-to solution for many home cooks.
To use a vinegar solution effectively, start by preparing a mixture of cold water and a splash of white vinegar. The ratio should be about 1 tablespoon of vinegar per 1 cup of water, ensuring it’s diluted enough to avoid overpowering the mushrooms with a vinegary taste. Submerge the mushrooms in this solution for 10–15 minutes, allowing the acidity to work on the odor-causing compounds. After soaking, rinse the mushrooms thoroughly under cold water to remove any residual vinegar and pat them dry with a clean cloth or paper towel.
While this method is generally effective, it’s important to note that vinegar may alter the texture of delicate mushrooms slightly. For varieties like shiitake or button mushrooms, this change is minimal, but more fragile types, such as enoki or oyster mushrooms, may become softer. Additionally, if the fishy smell persists after soaking, it could indicate more significant spoilage, and the mushrooms should be discarded to avoid food safety risks.
The vinegar solution is particularly useful for salvaging mushrooms that have been stored improperly or are nearing the end of their freshness. It’s a practical fix for those who prefer not to waste food but still want to ensure their ingredients are safe and pleasant to use. Pairing this method with proper storage practices, such as keeping mushrooms in a paper bag in the refrigerator, can help prevent odors from developing in the first place.
In summary, a vinegar soak is a straightforward and effective way to neutralize a slightly fishy smell on mushrooms. With the right dosage and technique, it can restore mushrooms to a usable state, though it’s not a guarantee for heavily spoiled produce. For best results, act quickly at the first sign of odor and always prioritize food safety.

Baking soda scrub: Use baking soda paste to clean and deodorize mushroom surfaces
Mushrooms can sometimes develop off-putting odors, including a slightly fishy smell, which may deter even the most enthusiastic forager or home cook. A baking soda scrub offers a simple, effective solution to this problem, leveraging its natural deodorizing and cleaning properties. Baking soda, or sodium bicarbonate, is a mild alkali that neutralizes acidic compounds responsible for unpleasant odors. When combined with water to form a paste, it becomes a gentle yet powerful tool for cleaning mushroom surfaces without damaging their delicate texture.
To create a baking soda scrub, mix 1 tablespoon of baking soda with enough water to form a thick paste—roughly 1 teaspoon of water should suffice. The consistency should be spreadable but not runny, allowing it to adhere to the mushroom’s surface. Gently apply the paste to the mushrooms using your fingers or a soft brush, ensuring even coverage. Focus on areas where the odor seems most concentrated, often the gills or crevices. Let the paste sit for 5–10 minutes to allow the baking soda to neutralize the odor-causing compounds.
While the scrub is effective, caution is necessary to avoid over-cleaning, which can alter the mushroom’s texture or flavor. After the paste has sat, rinse the mushrooms thoroughly under cold water to remove all traces of baking soda. Pat them dry with a clean cloth or paper towel, as excess moisture can promote spoilage. This method is particularly useful for wild mushrooms or store-bought varieties that have developed an unwanted smell due to improper storage or age.
Compared to other deodorizing methods, such as vinegar or lemon juice, baking soda is gentler and less likely to leave a residual taste. Its mild abrasiveness also helps remove surface impurities without requiring harsh chemicals. For best results, use this method immediately after detecting the fishy odor, as prolonged exposure to off-putting smells can make mushrooms less palatable. With its simplicity and effectiveness, a baking soda scrub is a practical, eco-friendly solution for restoring mushrooms to their natural, earthy aroma.

Lemon juice rinse: Apply lemon juice to eliminate fishy smell and refresh mushrooms
A slightly fishy smell on mushrooms can be off-putting, but it’s often a sign of mild spoilage or improper storage. Lemon juice, with its natural acidity and antimicrobial properties, offers a simple yet effective solution. Its citric acid breaks down odor-causing compounds, while its fresh scent masks lingering smells, making it a dual-action remedy for reviving mushrooms.
Application Method: Start by diluting fresh lemon juice with an equal amount of water to avoid overpowering the mushrooms’ natural flavor. Gently rinse the mushrooms in this solution for 10–15 seconds, ensuring even coverage.

Drying techniques: Pat dry with paper towels or air-dry to prevent sogginess
Mushrooms with a slightly fishy smell often result from improper storage or exposure to moisture, which can lead to bacterial growth or spoilage. While washing can help remove surface contaminants, it’s crucial to dry them properly afterward to avoid sogginess, which ruins texture and accelerates decay. Two primary drying techniques stand out: patting dry with paper towels or air-drying. Each method has its merits, but the choice depends on time constraints and the intended use of the mushrooms.
Pat Dry with Paper Towels: A Quick Fix
For immediate use, patting mushrooms dry with paper towels is the most efficient method. Gently blot the surface to absorb excess moisture without bruising the delicate flesh. Avoid rubbing, as mushrooms are porous and can tear easily. This technique is ideal for recipes requiring firm textures, like sautéing or grilling. For larger batches, use multiple layers of paper towels and flip the mushrooms to ensure thorough drying. While this method is faster, it may not be as eco-friendly due to paper waste, so consider reusable cloth towels if sustainability is a priority.
Air-Dry: Patience for Perfection
Air-drying is a slower but hands-off approach that preserves the mushroom’s natural structure and flavor. Place the washed mushrooms on a clean kitchen towel or a wire rack in a well-ventilated area, ensuring they are not overcrowded. Allow them to dry at room temperature for 1–2 hours, depending on humidity levels. This method is particularly suitable for recipes where moisture content is critical, such as stuffing or baking. However, avoid leaving mushrooms to air-dry for too long, as they can become overly dry and brittle.
Comparative Analysis: Which Method Wins?
The choice between patting dry and air-drying hinges on practicality and desired outcome. Paper towels offer speed and convenience, making them ideal for busy cooks or last-minute preparations. Air-drying, while time-consuming, provides a gentler approach that maintains the mushroom’s integrity. For instance, if you’re preparing a delicate mushroom risotto, air-drying might yield better results. Conversely, a quick stir-fry benefits from the efficiency of paper towels.
Practical Tips for Optimal Results
Regardless of the method chosen, always handle mushrooms with care to avoid damage. If using paper towels, press lightly rather than scrubbing. For air-drying, ensure the environment is free from direct sunlight or heat sources, which can cause uneven drying. Additionally, consider the mushroom variety—thicker types like portobellos may require more drying time than delicate oyster mushrooms. By mastering these techniques, you can effectively remove unwanted odors and maintain the mushrooms’ texture, ensuring they enhance your dishes rather than detract from them.
