Mushrooms are a staple in many cuisines and can be grilled, roasted, seared, or basted in butter. However, they often get a bad reputation for being soggy, slimy, or rubbery. This is usually due to improper preparation or storage. Mushrooms have a high water content, and their spongy texture is due to this moisture being released when exposed to heat. To avoid soggy mushrooms, it is important to cook them correctly and avoid steaming them. Additionally, storing mushrooms in a sealed container can lead to a slimy and wrinkly texture, so it is recommended to let them breathe by storing them in an unsealed paper bag in the refrigerator.

What You'll Learn
Mushrooms are spongy due to their high water content
Mushrooms are a unique type of fungus that boasts a high water content, contributing to their spongy texture. This moisture content is responsible for their characteristic springy and plump feel when fresh. However, when exposed to heat during cooking, the high moisture content can seep out, resulting in soggy or rubbery mushrooms. This loss of moisture during cooking can be prevented by properly drying the mushrooms before exposing them to heat.
The veil, a thin, spongy, white tissue found around the underside of the mushroom cap, is a natural part of the mushroom and plays a protective role for the gills until they release their spores. This tissue, also known as "the veil," is perfectly edible and adds to the overall sponginess of the mushroom.
To avoid soggy mushrooms, it is crucial to store them correctly. While sealed containers can lead to slimy and wrinkled mushrooms, storing them in paper bags with a damp paper towel can help maintain freshness. Additionally, allowing the mushrooms to breathe while keeping them in the refrigerator is essential.
When cooking mushrooms, it is advisable to avoid adding salt too early as salt draws out moisture, leading to steamed mushrooms. Instead, seasoning should be done towards the end of the cooking process. To achieve crispy mushrooms, it is recommended to use a heavy, high-quality pan, such as cast iron, and allow it to heat up properly before adding the mushrooms.

Fresh mushrooms should be dry, crisp and firm, not spongy
Fresh mushrooms should be dry, crisp, and firm, and never spongy. Mushrooms have a high water content, and when fresh, they should be plump, solid, smooth, and firm with a light earthy smell. If your mushrooms feel soft, soggy, or spongy, or are floppy, then they have begun to decompose and are not safe to eat.
To test a mushroom for freshness, you need to look at it carefully, touch it to check it’s still firm, and smell it. Some telltale signs that mushrooms are bad include a slimy film, stickiness, or a strong smell. Slimy mushrooms are often the result of being kept in the fridge for too long. If your mushrooms have developed wrinkles, it means they are getting old and dehydrated. If they have lots of wrinkles and look shrivelled, it’s safer not to eat them.
Mushrooms need to breathe, so storing them in a sealed container will result in a slimy and wrinkly texture. It is recommended to store mushrooms in a paper bag with the top loosely rolled up inside the refrigerator. Another way to store mushrooms is to use plastic bags lined with paper towels to help capture moisture. Make sure to change the towels regularly if you don't plan to use your mushrooms right away.
When cooking mushrooms, avoid washing them as the added moisture can cause them to spoil more quickly. If you do wash them, use a tea towel or paper towels to pat them dry. If you have time, allow them to sit on a fresh towel for an hour or so to dry even more completely. Cooking damp mushrooms causes them to steam as the water evaporates, resulting in a rubbery texture. To achieve crispy mushrooms, resist the urge to stir them and allow the liquid to fully evaporate before they get super brown.

Cooking mushrooms can make them spongy
Mushrooms are full of water, which gives them their spongy texture. However, when exposed to heat, this liquid begins to seep out. If the mushrooms are cooked on high heat, they may burn if there is not enough oil or butter in the pan. To avoid this, keep adding fat in small doses throughout the cooking process.
However, adding too much fat can also be detrimental. If the pan is too greasy, the mushrooms will fry, resulting in a soggy texture. Therefore, it is important to find a balance when adding fat to the pan.
Additionally, overcrowding the pan should be avoided. Mushrooms need enough room for their liquid to evaporate. If they are packed in too tightly, they will steam, leading to a spongy texture.
Another common mistake that can result in spongy mushrooms is stirring them too frequently. Stirring prevents proper caramelization, which is essential for achieving a crispy texture. Instead of stirring, resist the temptation and allow the mushrooms to become golden-brown before adding any liquid to the pan.
Finally, seasoning the mushrooms too early can also make them soggy. Salt draws out moisture from the mushrooms, and if enough salt is added, the mushrooms will begin to steam. Therefore, it is best to wait until the mushrooms are completely cooked before seasoning them.

Mushrooms should be stored correctly to prevent them from becoming spongy
Mushrooms have a high water content, which gives them their spongy texture. When exposed to heat, this moisture seeps out, and if not cooked properly, can result in soggy, rubbery mushrooms. To prevent this, it is important to store mushrooms correctly and prepare them in a way that allows the liquid to fully evaporate before they get too brown and crispy.
Firstly, when storing mushrooms, it is important to let them breathe. Keeping them in a sealed container will result in a slimy and wrinkly texture. Instead, store them in an unsealed and upright paper bag in the fridge. You can also use plastic bags lined with paper towels to help capture moisture, ensuring that you change the towels regularly.
Secondly, when preparing mushrooms for cooking, do not wash them until you are ready to cook them. If you do choose to wash your mushrooms, use a damp paper towel with a 50/50 mix of water and lemon juice. The lemon water helps break down the grit and prevents the mushrooms from turning brown. After washing, pat the mushrooms dry with a firm but gentle hand using a tea towel or paper towels.
Thirdly, when cooking mushrooms, make sure your pan is properly heated before adding them. Cooking mushrooms in a pan that is not properly heated will cause them to boil and steam in their own released moisture, resulting in a rubbery texture. Preheat your skillet over medium to medium-high heat for 2-3 minutes, then add oil or butter and wait for it to ripple or get frothy before placing in the mushrooms. You should hear a sizzle as soon as you toss them in, indicating that the skillet is evenly heated. Additionally, avoid overcrowding the pan, as this leaves little room for air and heat to circulate, causing the mushrooms to become mushy.
Finally, when sautéing mushrooms, resist the temptation to stir them too frequently. Allow them to become golden-brown and properly caramelized before stirring. Constantly stirring the mushrooms will result in rubbery, gray nubbins instead of crispy, golden 'shrooms.

The veil, a thin, spongy tissue, is a normal part of a mushroom
Mushrooms are spongy because of their high moisture content. When exposed to heat, this moisture begins to seep out, which can ruin the flavour and texture of dishes.
The veil is a thin, spongy tissue that is a normal part of a mushroom's anatomy. It is a temporary structure that forms early in the mushroom's life and serves a protective role. It is also known as the "velum". The veil acts as a safeguarding cloak, protecting the gills and locking in moisture until the mushroom is ready to release its spores.
The veil is composed of a network of interwoven hyphal threads, the building blocks of fungal structures. These threads weave together to form a thin membrane enveloping the mushroom's immature structures, specifically the cap and stalk. The universal veil can create a dense protective barrier around the entire immature fruiting body, while the partial veil is a finer membrane that shields the developing spore-producing surfaces.
The breaking of the veil is a crucial moment in a mushroom's life cycle, marking its transition into the spore-releasing phase. As the cap expands, the veil's tissue stretches, thinning and eventually tearing due to the pressure. The remnants of the partial veil can form various structures, the most common of which is the annulus or ring, a circular structure around the stalk.
