Mushrooms Absorb Water: How And Why?

do mushrooms soak up water

Mushrooms are known to be porous and absorbent, leading to the popular belief that they should not be washed. However, this is only partially true. While some mushrooms, like enoki and wild mushrooms, absorb a lot of water and should be cleaned with a brush or damp cloth, others, like champignon, can withstand rapid washing under running water. The key is to avoid soaking mushrooms in water for an extended period and to dry them promptly after washing. Additionally, cooking methods play a role, with higher temperatures allowing moisture to evaporate rapidly, preventing waterlogged mushrooms and preserving taste and aroma.

Mushrooms absorb water when washed, but not much if they're quickly rinsed

For years, it has been advised that mushrooms should not be washed with water because they are porous and will absorb the liquid, becoming waterlogged. Instead, it is recommended to brush off clumps of dirt with a paper towel, cloth, or brush. However, this belief has been challenged, and it appears that mushrooms do not absorb much water if they are quickly rinsed.

Some sources suggest that the absorbency of mushrooms depends on the type of mushroom, with Enoki mushrooms, for example, absorbing more water than others. Champignon mushrooms, on the other hand, can withstand rapid washing under running water. For other varieties, such as porcini mushrooms, it is recommended to use a brush or damp cloth to clean them.

When washing mushrooms, it is important not to leave them in the water for a prolonged period. A quick dunk or rinse under running water is sufficient to clean them without causing excessive water absorption. It is also suggested that washing mushrooms with water can prevent them from absorbing too much oil when sautéing, as the water will evaporate first.

Additionally, the cooking method can impact water absorption. Cooking mushrooms at a higher temperature will cause the water to evaporate more rapidly, preventing the mushrooms from becoming waterlogged. This method can also create a caramelized crust for added flavor.

In summary, while mushrooms do absorb water, a quick rinse or dunk under running water will not cause them to absorb excessive amounts. The key is to avoid soaking them and to dry them promptly after washing. The type of mushroom and cooking method also play a role in how much water they absorb.

Mushrooms should be dried after washing to avoid affecting their texture

Mushrooms are porous fungi that can absorb water and become waterlogged. The amount of water absorbed depends on the type of mushroom, with some varieties such as enoki mushrooms absorbing more water than others. Champignon mushrooms, for example, have less compact fibres and can withstand rapid washing under running water. However, other varieties like noble porcini mushrooms require slower and more meticulous cleaning methods.

It is recommended to avoid soaking mushrooms in water for prolonged periods. Instead, they can be cleaned by gently washing them under a low stream of water, using a colander to spray off the dirt, or wiping them with a damp paper towel or cloth. After washing, it is crucial to dry the mushrooms promptly to prevent them from absorbing too much water and altering their texture. A salad spinner or a towel can be used for drying.

If mushrooms absorb too much water, cooking them at a high temperature can help evaporate the excess moisture, preserving their taste and aroma. Chef Lucas Sin recommends boiling the mushrooms in water and then adding oil once the liquid has almost disappeared to create a caramelized crust. This technique saturates the mushrooms with water, enhancing their flavour, and then reduces the liquid to achieve the desired texture.

Additionally, when sautéing mushrooms, it is essential to use a high-temperature setting and ensure the pan is not too dry to prevent the mushrooms from burning. Mushrooms are highly absorbent and will absorb fat quickly, so adding oil or butter during cooking is crucial. By drying mushrooms after washing and using appropriate cooking techniques, their texture can be maintained while still benefiting from their water absorption properties to enhance flavour.

Mushrooms cooked in water can be more flavoursome

It is a widely held belief that mushrooms should not be washed before cooking as they will absorb the water and become waterlogged. However, this is only partially true. While some mushrooms, such as enoki and porcini, do absorb a lot of water and should be washed quickly and dried before use, others like champignon can withstand rapid washing under running water. The key is not to leave them in the water for too long.

When it comes to cooking, some chefs recommend adding water to mushrooms to enhance their flavour. Chef Lucas Sin, for example, suggests that mushrooms should be cooked in water to create a more flavoursome final product. He recommends washing the mushrooms, placing them in a wok or skillet, and adding enough water to cover them. The mushrooms are then boiled with seasoning for about 15 minutes. The water is allowed to reduce, and oil is added before it burns, creating a caramelized crust on the mushrooms.

This method of cooking mushrooms in water can be beneficial for enhancing their flavour and creating a desirable texture. By boiling the mushrooms in water, you are able to saturate them with moisture, which can bring out their natural essence. Additionally, the water helps to regulate the temperature and prevent burning while cooking, especially when using high heat.

However, it is important to note that mushrooms are highly absorbent, and they will release their water content when cooked. Therefore, when cooking mushrooms in a pan, it is recommended to use medium-high or high heat to allow the water to evaporate and give the mushrooms a nice brown colour. It is crucial to ensure that all the water has evaporated before removing them from the heat.

In summary, while it is generally advised not to soak mushrooms to avoid waterlogging, cooking them in water can be a technique to enhance their flavour and texture. The key is to control the amount of water and cooking time to prevent waterlogging while maximizing flavour.

Mushrooms absorb fat quickly when cooked on high heat

Mushrooms are like sponges, absorbing a lot of water and fat. While this is a desirable quality when cooking with fat, it can be a problem when cleaning the mushrooms. Mushrooms should be cleaned with a damp paper towel or brush, rather than being washed under running water, as they will become waterlogged.

When cooked on high heat, mushrooms absorb fat quickly and can burn if there is not enough oil or butter in the pan. Therefore, it is important to keep an eye on the mushrooms while they cook and add more fat if the pan looks too dry. On the other hand, cooking mushrooms on low heat will cause them to simmer in their liquid. Medium-high or high heat will evaporate the liquid and give the mushrooms a nice brown color.

To avoid using too much fat, it is recommended to use a non-stick pan and add salt and pepper to the mushrooms as you cook them. This will help the mushrooms shed some of their water and prevent them from sticking to the pan. Additionally, you can amplify the flavor with aromatics like garlic, shallots, and thyme, or use healthier fats like olive oil.

If you are concerned about the amount of fat absorbed by the mushrooms, you can also try cooking with dried mushrooms instead of fresh ones. Dried mushrooms can be reconstituted in hot water and then added to dishes like risotto. The resulting water can be used as a flavorful broth for soups or risotto as well.

Wild mushrooms are like sponges and will get waterlogged if washed

Wild mushrooms are highly absorbent, much like sponges, and will get waterlogged if washed. This is why it is generally recommended to avoid soaking mushrooms in water. However, it's important to note that not all mushrooms are the same, and some varieties can withstand quick rinses under running water without absorbing too much moisture. For example, Champignon mushrooms have less compact fibres and can be quickly washed.

The traditional advice has been to brush away dirt from mushrooms instead of rinsing them with water. This method can be time-consuming and may not remove all the dirt, especially from small crevices. While it is true that wild mushrooms can absorb water and become waterlogged, a gentle and quick rinse under a low stream of water, followed by immediate drying, can effectively clean them without causing waterlogging.

Some sources suggest that the concern about water absorption may be exaggerated. A quick dunk or shower can save time and effectively clean mushrooms. It is important to dry them promptly after washing to minimise any impact on their texture. Additionally, cooking methods can be adjusted to account for any additional moisture absorbed during cleaning.

When dealing with smaller mushrooms, such as honey fungus, it is recommended to remove visible soil first and then use a high-pressure nebuliser filled with water, ensuring immediate drying afterward. For prized mushrooms, a more tedious but thorough cleaning method is preferred, using a damp brush or cloth to carefully wipe away dirt without submerging the mushrooms in water.

Ultimately, while wild mushrooms can absorb water and should not be soaked, a quick rinse followed by drying can be a safe and effective cleaning method. The specific variety of mushroom and personal preference will influence the chosen cleaning technique.
