How To Wash Mushrooms: Do's And Don'ts

There are many opinions on whether or not to wash mushrooms. Some people believe that washing mushrooms can make them slimy and less flavorful, while others argue that a quick rinse won't affect the taste and is necessary to remove dirt and bacteria. Some recommend using a brush or damp cloth to clean mushrooms, while others say it's fine to give them a quick rinse as long as they are cooked immediately afterward. Ultimately, it's a matter of personal preference, but it's important to remember that mushrooms should be cleaned in some way before cooking to remove any dirt or debris.

Mushrooms should be washed before cooking

Mushrooms are delicate and people often debate the best way to clean them. Some people believe that washing mushrooms can make them slimy and less flavourful, and that the best way to clean them is to scrape off the dirt or peel them. However, it is perfectly safe to wash mushrooms before cooking, and this is recommended to ensure they are free of dirt and debris.

Chefs like Alex Guarnaschelli and Alton Brown say it is okay to wash mushrooms. Guarnaschelli uses a knife or a damp cloth to remove visible dirt, but washes them if they are particularly dirty. Brown recommends rinsing mushrooms and drying them off before cooking. Harold McGee, a food historian and author, also recommends washing mushrooms, noting that they will not become soggy or have their flavour diluted.

Some people are concerned that washing mushrooms will make them absorb too much water, but this is a myth. Mushrooms are already high in moisture and do not absorb much additional water when washed. In fact, mushrooms can contain more water than you would expect from looking at them, and they shrink when cooked. Washing mushrooms will not significantly affect cooking time.

If you are concerned about water absorption, there are alternative methods to clean mushrooms. You can use a soft-bristled brush to gently scrub away dirt, or follow the technique championed by chef Emeril Lagassé: dip a small brush in water and brush the mushroom to use a minimal amount of water. You can also use a dry cloth, paper towel, or a pastry brush to wipe off dirt and grime.

However, it is important to note that washed mushrooms do not keep well and should be cooked immediately. This is because washing can damage the surface cells and cause discoloration. Therefore, it is recommended to wash mushrooms right before using them, rather than storing them after washing.

Mushrooms absorb water when washed

There is a common belief that mushrooms should not be washed because they will absorb water and become waterlogged. However, this is not entirely true, and it depends on the type of mushroom. Some mushrooms, like enoki and lion's mane, absorb more water than others. In general, mushrooms do not absorb a significant amount of water if they are given a quick rinse and dried properly.

Mushrooms are porous fungi with a high water content, often exceeding 90%. They lack a proper fluid circulation system, so they absorb nutrients directly through their walls. This means that they will absorb some water if washed, but the amount is negligible if they are not soaked for a prolonged period. A quick dunk or rinse under running water can effectively clean mushrooms without causing them to become waterlogged.

It is important to clean mushrooms before cooking to remove any dirt or debris. The traditional method of cleaning mushrooms involves using a brush, a damp cloth, or a paper towel to wipe or brush away visible dirt. However, these methods can be time-consuming and may not remove all the dirt, especially from crevices. Washing mushrooms with water is a faster and more effective way to clean them thoroughly.

After washing, it is crucial to dry the mushrooms thoroughly. They can be blotted with a towel, patted dry, or even spun in a salad spinner. Proper drying helps minimize the amount of water absorbed and prevents the mushrooms from becoming soggy. Once cleaned and dried, the mushrooms should be cooked immediately, as washed mushrooms do not keep well.

While some chefs and culinary experts advise against washing mushrooms, others argue that it is perfectly acceptable. The key is to use the right technique and avoid soaking the mushrooms for too long. A gentle rinse or a quick dunk, followed by thorough drying, will ensure that the mushrooms absorb minimal water and retain their texture and flavor.

Mushrooms can be wiped clean instead of washing

There are several ways to wipe mushrooms clean. One way is to use a soft-bristle brush to gently scrub away dirt. Another method is to dip a small brush in water and then brush the mushroom to use a minimal amount of water for cleaning. A third option is to use a knife or a damp cloth to remove visible dirt. If you are buying boxed mushrooms from a grocery store, they are most likely already clean as most mushrooms are grown in indoor farms. Unless you see any dirt, you can start cooking. If you do find dirt, grab a dry cloth, paper towel, or a pastry brush to wipe off the dirt.

Some people prefer to wash their mushrooms, especially if they are visibly dirty. If you choose to wash your mushrooms, it is recommended to do so right before cooking and to dry them off afterward. It is also important to note that mushrooms should not be soaked, but rather given a quick rinse under warm water.

There are some potential risks associated with not washing mushrooms. While cultured mushrooms are typically grown on sterilized substrates, they may still contain bacteria or other contaminants that can be removed by washing. Additionally, eating unwashed fruits and vegetables may increase the risk of certain diseases such as listeria, salmonella, and toxoplasmosis. Ultimately, the decision to wash or wipe mushrooms clean is a matter of personal preference, and both methods can be effective in removing dirt and debris.

Mushrooms should be washed right before cooking

While some people prefer to brush off their mushrooms or peel them, it is perfectly fine to wash them. Food historian Harold McGee and author of 'On Food and Cooking' disproved the belief that mushrooms will absorb too much water if they get wet. He, along with Robert Wolke, Kenji Lopez Alt, and Alton Brown, found that mushrooms absorb an insignificant amount of water that does not significantly affect cooking time. In fact, mushrooms are already mostly water, and lose little, if any, flavour from a brief rinse.

If you are still hesitant to wash your mushrooms, you can use a damp cloth, paper towel, or brush to wipe off any dirt. However, if your mushrooms are particularly dirty, it is best to give them a quick rinse under lukewarm water, then blot them with a towel and cook them right away.

It is worth noting that cultivated mushrooms are typically grown on a sterilized substrate, so the risk of consuming harmful bacteria is minimal. However, wild mushrooms may require a more thorough cleaning, as they tend to hold more dirt in their crevices and creases.

Mushrooms are already high in moisture

Mushrooms are a delicate food item with a high water content, and there are differing opinions on the best way to clean them. Some people believe that washing mushrooms is unnecessary and can even be detrimental, as it may make them slimy and less flavourful. This is because mushrooms are already high in moisture, so washing them can affect their texture and cooking time.

However, others argue that washing mushrooms is perfectly fine and can help remove dirt and bacteria. It is worth noting that cultivated mushrooms are typically grown on a sterilised substrate, so the risk of harmful bacteria may be minimal. Nonetheless, some people prefer to err on the side of caution and give their mushrooms a quick rinse before cooking.

Those who choose to wash their mushrooms recommend doing so right before cooking, as this helps prevent discolouration and ensures the mushrooms are not stored while wet, which can cause them to go bad faster. A gentle rinse under warm water, followed by a dry with a towel, is often sufficient. Some people also use a soft-bristled brush or a damp cloth to remove visible dirt.

It is important to note that different varieties of mushrooms may have specific cleaning requirements. Wild mushrooms, for example, may require a more thorough washing or even soaking to remove dirt and debris from their crevices. Cultivated mushrooms, on the other hand, are often relatively clean and may only need a quick rinse or wipe with a damp cloth. Ultimately, the decision to wash or not wash mushrooms comes down to personal preference and the specific type of mushroom being prepared.
