Cleaning Mushrooms: A Step-By-Step Guide

how should you clean mushrooms

There are many different opinions on how to clean mushrooms. Some people say that you should never wash mushrooms because they absorb a lot of water, which can make them soggy and mushy. Others say that a quick rinse is enough to clean them without absorbing too much water. The best method for cleaning mushrooms depends on the type of mushroom and whether they are cultivated or wild. Cultivated mushrooms are grown in sterile compost and are relatively clean, so they only need a quick brush or rinse to remove any excess dirt. Wild mushrooms, on the other hand, may have more dirt and grit, so they may need to be washed more thoroughly.

Brushing vs washing

There are two schools of thought when it comes to cleaning mushrooms: brushing and washing. The method you choose depends on the type of mushroom, how it was sourced, and how you intend to use it.

Brushing

Brushing is suitable for wild mushrooms or those bought from a farmer's market. These mushrooms are often more expensive and less gritty, so brushing is a gentler method that won't damage the product. Brushing is also a good option for store-bought mushrooms like white buttons or cremini, as the dirt on these mushrooms is actually sterile manure, which can be brushed off without getting the mushrooms too wet.

Washing

Washing mushrooms is a good option for most store-bought mushrooms. Mushrooms are porous and can absorb water, so it's important to avoid soaking them. A quick rinse under cold water, followed by patting them dry with a towel, is usually sufficient. Washing is essential for wild mushrooms like morels, which can be very dirty and may need to be soaked to remove dirt and insects.

Both brushing and washing can be effective methods for cleaning mushrooms. Brushing is ideal for more delicate, expensive mushrooms or those with loose dirt that can be easily removed. Washing is suitable for most store-bought mushrooms and essential for very dirty wild mushrooms. Ultimately, the method you choose depends on your personal preference and the specific type of mushroom you are working with.

How to wash mushrooms with exposed gills

There are several methods for cleaning mushrooms with exposed gills, such as portobellos, oyster mushrooms, or shiitakes. The key is to avoid waterlogging the mushrooms, as they are very absorbent and can become soggy and rubbery. Here are some detailed steps to ensure your mushrooms are clean and safe to eat:

Firstly, it is recommended to clean mushrooms just before cooking. Exposure to excess moisture can speed up rotting, so it is best to clean them right when you need them.

If your mushrooms are foraged or wild, they will likely have more grit and require a thorough wash. Fill a large bowl with cold water and add a few mushrooms at a time. Swirl them around gently for about ten seconds to loosen any dirt. Immediately remove them from the water and pat them dry with a clean, lint-free towel. Lay them out with the caps facing up and allow them to air-dry completely before cooking. If you notice any stubborn dirt, use a damp paper towel to wipe it off. You can also use extra-soft toothbrushes or baby brushes to gently clean the gills and smaller cavities.

However, if your mushrooms are cultivated or purchased from a grocery store, they are likely quite clean already. In this case, a quick dry brush may be sufficient. Use a paper towel, pastry brush, or mushroom brush to gently brush away any visible dirt or compost from the surface of the mushrooms. Avoid using water unless there are stubborn patches of dirt and grime. If necessary, use a damp cloth or paper towel to wipe down the mushrooms, ensuring you dry them thoroughly before cooking.

Additionally, when storing mushrooms, it is best to keep them unwashed in the refrigerator. Use a paper bag or the original packaging, as mushrooms need to breathe, and plastic bags can lead to condensation and slime.

Remember, the goal is to remove dirt and grime without introducing too much moisture, so your mushrooms remain dry and absorb flavours during cooking.

How to wash mushrooms without exposed gills

There are many different opinions on the best way to clean mushrooms. However, it is generally agreed that mushrooms without exposed gills, such as button, cremini, or porcini mushrooms, can be rinsed in cold water.

Firstly, fill a large bowl with cold water and have a clean, lint-free towel nearby. Then, add a few mushrooms at a time to the water, swirling them around for about ten seconds to loosen any dirt. You can also gently rub them with your fingers to dislodge stubborn particles. Immediately after, place them on a towel, patting them dry and laying them out (caps up) to air-dry. If you still see some dirt, use a damp paper towel to wipe it off.

Make sure not to let the mushrooms soak for too long, as they tend to soak up liquid like a sponge and can become slimy, mushy, or waterlogged. Instead of soaking, you can also rinse the mushrooms in a colander and then lay them out on a towel to dry.

If you are cleaning mushrooms with exposed gills, such as portobellos, oyster mushrooms, or shiitakes, it is recommended to use a brush or paper towel to remove dirt, rather than rinsing them in water.

How to dry mushrooms after washing

There are varying opinions on the best way to clean mushrooms. Some sources suggest brushing them with a dry cloth or brush, while others recommend rinsing them with water. The best method may depend on the type of mushrooms and how they will be used.

If you choose to wash your mushrooms with water, it is important to dry them thoroughly afterward to prevent them from becoming slimy or waterlogged. Here is a step-by-step guide on how to dry mushrooms after washing:

  • After rinsing your mushrooms with cold water, shake off any excess liquid. You can do this by placing them in a colander and giving it a gentle shake.
  • Use a clean, lint-free towel to pat the mushrooms dry. Try to get them as dry as possible, patting and rubbing them gently but firmly.
  • Lay the mushrooms out on a paper towel or a clean kitchen towel, with the caps facing up. This will help to absorb any remaining moisture and speed up the drying process.
  • Allow the mushrooms to air-dry completely before cooking or storing them. It is important to ensure they are thoroughly dried to prevent them from becoming slimy.
  • If you are using wild mushrooms or foraged mushrooms, which may have more dirt or grit, you can also use a damp paper towel to wipe them down after washing. This will help to remove any stubborn dirt particles.
  • If you want to be extra thorough, you can use a soft-bristled brush, such as a toothbrush, to gently brush the mushrooms after washing and drying. This will help remove any remaining dirt or debris.

Remember, it is important to dry mushrooms as thoroughly as possible after washing to prevent excess moisture from affecting their texture and flavour.

How to store cleaned mushrooms

Mushrooms are porous and tend to soak up liquid like a sponge. If you want to keep them for several days or even up to a week, they should be stored in a paper bag in the fridge. Paper bags are recommended because, as mushrooms age, they release water, and the paper bag will absorb that moisture, keeping the mushrooms' surface slime-free. If you only have a plastic bag, be sure to leave it partially open to ensure circulation.

If you have a large number of cleaned mushrooms, you can also freeze them. However, freezing mushrooms will likely compromise their texture, so it's best to use these in stocks or veggie burgers rather than frying them.

If you are planning to cook with your cleaned mushrooms right away, you can also store them in a colander and then immediately blot them with a towel.
