Mushrooms are known to have a high water content, and whether they are fresh or dried, they can hold water. When cooking, mushrooms tend to release water, and this is entirely normal. However, there are conflicting opinions on whether mushrooms absorb water when washed. Some sources claim that mushrooms are like sponges and will absorb water, while others argue that the amount of water absorbed is minimal compared to their initial water content. The type of mushroom may also be a factor, as certain varieties, such as enoki and lion's mane mushrooms, are said to absorb more water than others. To avoid waterlogged mushrooms, some recommend cleaning them with a damp paper towel or brush instead of washing them under running water.
| Characteristics | Values |
|---|---|
| Absorbency | Mushrooms are like sponges and absorb water when washed. However, the amount of water absorbed varies depending on the type of mushroom. |
| Water Content | Mushrooms naturally have a high water content, and this water is released when they are cooked. |
| Cooking Technique | To prevent mushrooms from becoming waterlogged, it is recommended to cook them on medium-high or high heat to evaporate the water and give them a nice brown color. Overcrowding the pan should be avoided as it can trap moisture and cause steaming. |
| Cleaning | Instead of washing mushrooms under running water, it is suggested to clean them with a damp paper towel or brush to remove dirt. Wild mushrooms, in particular, should not be washed as they can become slimy and waterlogged. |

Mushrooms are like sponges
When cooking mushrooms, it is best to slice them and let them air dry for a bit before cooking. Using a higher heat will help evaporate the moisture quickly. It is also important not to move them around in the pan too much.
Some people choose to wash mushrooms before cooking, but this is a contentious issue. Some sources suggest that washing mushrooms under cold running water quickly and easily removes dirt. However, others argue that washing mushrooms can make them slimy and waterlogged. Instead, it is recommended to clean them with a damp paper towel or brush them off with a pastry brush.
Dried mushrooms are very porous and will absorb fat, resulting in greasy mushrooms. On the other hand, wet mushrooms will not absorb as much oil and will brown beautifully.

How to wash mushrooms
There are several methods for washing mushrooms, and the best one for you will depend on the type of mushroom and how you intend to use them.
If your mushrooms are cultivated, they are likely to be relatively clean as they are grown in a sterile environment. In this case, you can simply brush off any remaining dirt with a dry towel or mushroom brush. If there are stubborn bits, use a damp paper towel to wipe them off.
If your mushrooms are wild, they are likely to have more dirt in their crevices and will need a more thorough wash. Fill a large bowl with cold water and add a few mushrooms at a time. Swirl them around in the water for about ten seconds, then remove them to a clean, lint-free towel. Pat the mushrooms dry and lay them out (caps up) to finish air-drying before washing the next batch.
If you are still concerned about dirt after washing, you can also peel mushrooms before cooking.
It is worth noting that mushrooms are very absorbent, and can easily become waterlogged if left to soak for too long. This can affect their texture and make them less suitable for certain recipes. Therefore, it is important to be gentle when washing mushrooms and to ensure they are patted dry before cooking.
Some sources suggest that wild mushrooms should not be washed at all due to their absorbency, and that they should be cleaned with a damp paper towel or brushed off with a pastry brush instead.

Mushrooms release water when cooking
Mushrooms are composed of up to 92% water. When cooked, they release this moisture, which can affect the cooking process and the final dish. This release of water is entirely normal, and the liquid can be used as a base for sauces or soups. However, if the mushrooms are overcrowded in the pan, they will steam in the excess moisture and may not brown properly.
To prevent this, cooks can slice mushrooms and let them air dry before cooking. A higher heat will also help to evaporate the liquid more quickly. Alternatively, some cooks recommend sweating the mushrooms in a dry pan first, to release their water, before adding oil or butter and turning up the heat. This prevents the mushrooms from absorbing too much fat and becoming greasy.
Some cooks prefer to wash their mushrooms before cooking, but this can make them waterlogged and slimy, especially wild mushrooms. Instead, it is recommended to clean them with a damp paper towel or brush. However, other cooks disagree and wash their mushrooms, but ensure they dry them before use.
Mushrooms are like sponges, and dried mushrooms will absorb water or fat. Therefore, it is best to avoid adding oil or butter at the beginning of the cooking process, and instead add it later, once the mushrooms have released their water and it has evaporated.

Evaporating mushroom water
Mushrooms are like sponges: they absorb water quickly. This is especially true of wild mushrooms. Therefore, it is recommended to clean them with a damp paper towel or brush them with a pastry brush instead of washing them under running water. If you do wash them, they can become waterlogged, slimy, and soggy.
However, some people still choose to wash their mushrooms. To do so effectively, fill a bowl with water and vigorously agitate the mushrooms in the water. Then, place them on a towel to dry. Alternatively, if you have a colander that fits into a bowl, you can place the mushrooms in the colander, put it into a bowl in the sink, and fill it with water.
When cooking mushrooms, it is normal for them to release water. To prevent excessive moisture, slice the mushrooms and let them air dry before cooking. You can also use a higher heat to help the moisture evaporate quickly. Avoid overcrowding the pan, as this can trap moisture and cause the mushrooms to steam. Instead, cook them in batches, ensuring there is only a single layer of mushrooms in the pan at a time.
When all the water has evaporated, the mushrooms will begin to sizzle and brown. At this point, you can add oil or butter to the pan and season the mushrooms as desired.

Cooking methods for cup mushrooms
Cup mushrooms, like all mushrooms, are like little sponges and will absorb any moisture. This means that they can get waterlogged if washed under running water. Instead, they should be cleaned with a damp paper towel or brushed with a pastry brush.
When cooking cup mushrooms, it is important to note that they will release their juices and cook in their liquid. This liquid should be allowed to evaporate before removing the mushrooms from the heat. Cooking cup mushrooms in a pan with a little water and then adding oil can make them less spongy and less likely to absorb the oil.
To cook cup mushrooms, heat a pan to a medium-high or high heat and add fat—either oil or butter. Olive oil will give the mushrooms a golden brown crust and flavour. Butter will give a lighter sauce. Enough fat should be added to generously cover the bottom of the pan. The mushrooms should then be added to the pan and left until they start to brown. They can then be seasoned with salt and pepper, and other ingredients such as garlic, lemon, thyme, and butter can be added.
It is important not to overcrowd the pan when cooking mushrooms as they need room for their liquid to evaporate. If they are packed in too tightly, they will steam. It is also important not to stir the mushrooms too much—they should be left to cook without stirring so that they can brown.
Cooked cup mushrooms can be stored in an airtight container in the fridge for up to 5 days or frozen for up to 6 months.
