Cleaning Sponge Mushrooms: A Step-By-Step Guide

how to clean sponge mushrooms

Sponge mushrooms, also known as morels, are a type of wild mushroom that can be foraged or bought from farmers' markets. They have a honeycomb texture and can be very dirty, so they require a thorough cleaning. Here's a step-by-step guide on how to clean sponge mushrooms properly: First, cut the mushroom into pieces. Then, submerge them in a bowl of cold water and agitate them to remove any dirt and insects. If the mushrooms are still dirty, a short soak in lightly salted water will help remove any remaining impurities. Finally, rinse the morels and pat them dry with a clean kitchen towel or paper towel. It is important to note that mushrooms are porous and can absorb water easily, so it is best to avoid soaking them for too long.

Removing dirt and insects

When it comes to removing dirt and insects from sponge mushrooms, there are several methods you can use. Firstly, it is important to determine whether your mushrooms are cultivated or wild. Cultivated mushrooms are typically cleaner and can often be simply brushed off with a dry towel or a mushroom brush, which is a small, round brush with soft bristles. If they appear clean and you are satisfied, you may not need to do anything further.

However, if your mushrooms are wild, or if they appear dirty, you will need to give them a quick wash. Wild mushrooms may harbour insects or have dirt and grit from the forest floor, so it is important to clean them thoroughly. Begin by cutting the mushrooms into pieces, which will make them easier to clean. You can then submerge the pieces in a bowl of cool water and agitate them to loosen any dirt or insects. If the mushrooms are very dirty, you may need to soak them in lightly salted water, which will help draw out any remaining dirt and insects. Change the water as needed until the water remains clear and free of debris.

After soaking or washing, be sure to dry your mushrooms thoroughly. You can use paper towels or a clean kitchen towel to pat them dry. Alternatively, you can use a salad spinner to dry them more efficiently. It is important to remove as much moisture as possible, as mushrooms are porous and will absorb water, which can affect their texture and cooking properties.

For sliced mushrooms, a quicker method is to place them in a colander and spray them with water, dislodging any dirt. Give the colander a few shakes and then pat the mushrooms dry. Remember, the key is to avoid soaking mushrooms for too long, as they will absorb water quickly.

Soaking in salted water

Mushrooms are porous, just like sponges, and will soak up moisture when washed in water. Therefore, it is important to know how to clean them without letting them get waterlogged.

To clean sponge mushrooms by soaking them in salted water, start by rinsing them in cool water to remove any visible dirt and insects. If the mushrooms look clean after rinsing, you can stop here. However, if they still appear dirty, you can soak them in salted water to remove any remaining dirt and insects.

To make the salted water solution, add one teaspoon of salt to a quart of water (about 5 ml of salt per liter of water). You can also add a pinch of garlic powder to the water, as some people believe it helps drive out bugs. Place the mushrooms in the salted water and soak them for 5-20 minutes. Be careful not to soak them for too long, as they may become soggy and lose some of their flavour.

After soaking, remove the mushrooms from the salted water and place them on a paper towel or a clean linen towel to drain and dry. Your sponge mushrooms are now clean and ready to be used in your favourite recipes!

Brushing vs washing

There are differing opinions on the best way to clean mushrooms. Some sources suggest brushing mushrooms, while others recommend washing them. So, which method is the best? Let's take a closer look at the pros and cons of each method.

Brushing Mushrooms

Brushing mushrooms involves using a tool known as a mushroom brush or a small brush with soft bristles to gently remove grit and dirt from the surface of the mushroom. This method is often recommended for store-bought mushrooms, such as white buttons or cremini mushrooms, which have been grown on sterile manure. The manure is the "dirt" that clings to the mushrooms, and while it is safe to consume, it may not be pleasant. Brushing can effectively remove this dirt if it is loose. However, some bits may be more firmly attached or hiding in the gills, making it challenging to ensure the mushrooms are thoroughly cleaned. Brushing is also a more time-consuming process compared to washing.

Washing Mushrooms

Washing mushrooms involves rinsing them in cool water or submerging them in a bowl of water to remove dirt and insects. This method is generally recommended for wild mushrooms or foraged mushrooms, which may have more dirt, grit, or bugs attached to them. Washing ensures that all the dirt and insects are removed, resulting in a thorough cleaning. However, one of the main concerns with washing mushrooms is the belief that they will absorb too much water and become waterlogged, affecting their texture and taste during cooking. However, some sources refute this claim, stating that mushrooms are mostly water, and a little extra water will not significantly alter their flavour or texture. Additionally, mushrooms lose moisture when exposed to heat, so any excess water will cook out.

In conclusion, both brushing and washing have their advantages and disadvantages. Brushing may be preferable for store-bought mushrooms with loose dirt, while washing is ideal for wild or foraged mushrooms to ensure thorough cleaning. Ultimately, the chosen method may depend on personal preference, the type of mushroom, and how they will be used in cooking.

Preparing wild mushrooms

Firstly, inspect the mushrooms for dirt and debris. If they are very dirty, you can wash them in a large bowl of cold water, swirling them around to loosen any dirt. Mushrooms are like sponges, so it is important not to let them soak for too long. After washing, dry the mushrooms with a clean towel, and leave them to air-dry. If there are stubborn bits of dirt, use a damp paper towel to wipe them off.

Alternatively, mushrooms can be brushed clean with a mushroom brush, which has soft bristles, perfect for cleaning delicate mushrooms. Twigs and leaves can be picked off, and bad spots can be trimmed away. If the mushrooms are very wet after cleaning, it is best to let them dry in the refrigerator for a day or two before cooking.

Some mushrooms, such as morels, can be soaked overnight in salted water to remove insects from cavities. This method also works for any foraged mushrooms that may be harbouring critters, but this is usually only an issue in summer. After soaking, the mushrooms should be rinsed, patted dry, and used in recipes.

When cooking mushrooms, it is important to manage their moisture content. Mushrooms are mostly water and act like sponges, so they can become too wet and slimy if they are washed or rained on. On the other hand, if they dry out too much, they can become like shoe leather. If they are too dry, they can be rinsed or soaked. If they are too wet, they can be stored in the refrigerator until they firm up again.

Mushrooms can be cooked in a variety of ways, including sautéing, grilling, roasting, or poaching. Sautéing is a good option for most mushrooms, but some, like boletes/porcini and amanitas, need a lighter touch. When sautéing, it is best to use a dry pan without oil, as oil locks in water content, and you want the mushrooms to release water for the best texture. Get the pan hot over medium-high heat and add a single layer of mushrooms. Be patient, as mushrooms are hard to overcook. They are done when lightly browned. If you are making a scramble, add the eggs at this point. For mushroom sauces, add the cream or tomato sauce.

Drying techniques

The best way to dry mushrooms is to use a salad spinner. If you don't have one, lay the mushrooms on a double layer of cotton dish towels and pat them dry. You can also use paper towels or a clean kitchen towel. Make sure to remove as much moisture as possible. If you're drying mushrooms in the wild, a mesh hanging rack is a great way to start the moisture loss, even under a well-placed tarp on a rainy day.

If you're drying morel mushrooms, wrap them loosely in damp paper towels or a damp, clean cotton cloth. Place the bundle in a bowl and store it in the refrigerator for up to three days, keeping the towels damp.

For wild foraged mushrooms, it is important to clean them well at the time of picking. Brush off any dirt with a soft brush or cloth, and avoid washing them to prevent moisture retention. If you're drying porcinis, they will take some time, so you'll need to lovingly go through each mushroom, checking for worms and preparing them for drying.

If you're planning to freeze your mushrooms, it's important to pat them dry as much as possible to remove most of the moisture before freezing. Frozen mushrooms can be stored for up to two months.
