Quickly Rehydrating Mushrooms: A Simple Guide

how to hydrate mushrooms fast

Dried mushrooms are a versatile and flavourful ingredient used in cooking. They are often used to add a rich, meaty, savoury note to dishes and are high in umami. Before using dried mushrooms, they need to be rehydrated in water. The typical recommendation is to soak them for 30 minutes, but some recipes may call for a longer period. If you are in a hurry, using warm or hot water can speed up the process, although this may extract more of the mushroom's flavour into the water. Once rehydrated, the mushrooms should be thoroughly cooked before eating, as the human stomach lacks the enzyme to digest chitin, a substance found in mushrooms.

Use hot water for faster rehydration

Dried mushrooms are a versatile ingredient that can be used in a variety of dishes, from soups and stews to pastas and salads. Before using dried mushrooms, they need to be rehydrated. One way to do this is by using hot water, which speeds up the rehydration process.

Using hot water to rehydrate mushrooms is a faster method compared to using room temperature or cold water. The warm water helps to soften the mushrooms more quickly, making them ready for use in a shorter amount of time. This is especially useful if you are in a hurry or forgot to soak the mushrooms in advance.

When using hot water for rehydration, simply place the desired amount of dried mushrooms in a bowl or container and cover them with hot water. You can use a plate or another object to keep the mushrooms submerged if needed. Let the mushrooms soak for at least 20 minutes, but you can also leave them for up to an hour if you want a longer soak.

While hot water speeds up the rehydration process, it's important to note that it can also extract more of the mushrooms' flavor into the soaking water. This means that some of the mushroom's flavor may be lost to the water, resulting in a milder taste. However, the soaking liquid that's produced can be just as valuable as the rehydrated mushrooms themselves. This flavorful liquid can be used in various dishes, such as soups, sauces, or anywhere you want to add a mushroomy boost.

After the mushrooms have softened, slowly drain the soaking liquid through a strainer lined with a coffee filter or paper towel. This will remove any remaining grit or sediment. You can then use the mushrooms in your desired recipe, making sure to thoroughly cook them as rehydration is not the same as cooking.

Use the soaking liquid for added flavour

The liquid that remains after rehydrating dried mushrooms is a flavourful broth that can be used in stocks, soups, sauces, and more. It's a great way to add depth of flavour to your dishes and make the most of your mushrooms.

To use the soaking liquid for added flavour, start by straining the liquid to remove any grit or dirt. Place a strainer over a bowl and line it with a coffee filter or paper towel. Pour the soaking liquid through the strainer and let it drain. You can then use this flavoured liquid in your recipes or store it for later use. It will keep in the refrigerator for about a week or in the freezer for up to three months.

The soaking liquid from rehydrated mushrooms can be used in various dishes, including soups, stews, sauces, pâtés, and gratins. It adds a rich, savoury note and enhances the umami flavour of your dishes. You can also use it in place of water or stock when cooking rice or grains to infuse them with flavour.

If you're using hot water to rehydrate your mushrooms, be aware that more of their flavour will be extracted into the soaking liquid. This isn't necessarily a bad thing, as it concentrates the flavour in the liquid, but it's something to keep in mind if you want more mushroom flavour in the mushrooms themselves. Room temperature water will extract less flavour from the mushrooms, leaving more flavour in the mushrooms for cooking.

The French press method, popularised by Win Son chef Trigg Brown, is an excellent way to rehydrate mushrooms and maximise the flavour of the soaking liquid. Simply place the dried mushrooms in a French press, cover them with hot water, and let them soak for 20 minutes to an hour. Then, slowly push down on the plunger to extract even more flavour from the mushrooms. This method ensures that the mushrooms are fully submerged and allows you to press out all the flavourful liquid.

Rinse mushrooms to remove grit

Dried mushrooms are a versatile ingredient that can be used in a variety of dishes, from soups and stews to pâtés and gratins. However, one of the biggest challenges when cooking with dried mushrooms is grit. Even a tiny amount of grit can ruin a dish, and cheap or low-grade mushrooms tend to be grittier.

Before cooking with dried mushrooms, it's important to inspect them for dirt and rinse them if necessary. To do this, place the mushrooms in a strainer and run them under the faucet for several seconds, tossing them to ensure all the grit is removed. You can also taste a mushroom, and if it has a gritty texture, you'll know that you need to rinse them.

After rinsing, the mushrooms are ready to be reconstituted with water, which will give them a tender texture. The amount of time needed to soak the mushrooms varies, but it is typically recommended to soak them for at least 30 minutes. Using warm or hot water will speed up the rehydration process, but it will also extract more of the mushrooms' flavor into the soaking water.

Once the mushrooms are fully rehydrated, they should be cooked thoroughly before consuming. This is because all mushrooms worth rehydrating contain chitin, a substance that human stomachs cannot digest.

Soak for 20 minutes to an hour

To hydrate mushrooms fast, you can use warm or hot water to soak them. The mushrooms will soften more quickly, but this method will also extract more of their flavour into the soaking water. If you want to retain as much flavour in the mushrooms as possible, opt for room-temperature water instead.

A French press is a great way to keep the mushrooms submerged in water. Fill a large French press with your mushrooms and cover them with hot water. Allow them to soak for 20 minutes to an hour. Then, slowly push down on the plunger, similar to how you would make coffee.

You can save the flavourful mushroom broth for stocks, braises, soups, stews, sauces, pâtés, or gratins. The mushrooms themselves can be used in ramen, risotto, or any dish that calls for fresh mushrooms.

Remember, this process only rehydrates the mushrooms and does not cook them. Be sure to thoroughly cook the mushrooms after rehydrating, as they contain chitin, a substance that human stomachs lack the enzyme to digest.

Cooking Mushrooms After Rehydrating

Dried mushrooms are a versatile and flavourful ingredient that can be rehydrated and cooked in a variety of ways. Firstly, it is important to note that rehydration is the first step to cooking with dried mushrooms. Dried mushrooms contain a substance called chitin, which human stomachs cannot digest, so it is crucial to thoroughly cook mushrooms after rehydrating them.

Rinsing and Straining Mushrooms:

Before cooking, it is essential to remove any grit from the mushrooms. Place the mushrooms in a strainer and rinse them under cold water, ensuring all the grit is gone. You can also use a coffee filter or paper towel to strain the mushroom soaking liquid, which can be saved for later use in stocks or sauces.

Chopping Rehydrated Mushrooms:

Rehydrated mushrooms can be slimy, so it is recommended to chop them into small pieces before cooking. This helps to avoid having large, slimy pieces in your mouth.

Cooking Methods:

There are several ways to cook rehydrated mushrooms:

  • Sautéing: You can sauté the mushrooms in butter or olive oil. Heat up some butter or oil in a pan and add the chopped mushrooms. Sauté until they are cooked to your desired level of doneness.
  • Stir-frying: Rehydrated mushrooms can be stir-fried in a wok with neutral oil and soy sauce. This method is suitable for mushrooms like morels and black fungus.
  • Adding to Soups and Stews: Rehydrated mushrooms can be added directly to soups, stews, or broths. They will continue to cook and absorb the flavours of the soup or stew.
  • Using in Risotto: Dried mushrooms can be rehydrated and used in risotto dishes, adding a boost of flavour.

Using the Soaking Liquid:

The liquid used to rehydrate the mushrooms is flavourful and can be used in various ways:

  • Stocks and Braises: The mushroom soaking liquid can be used as a base for stocks, braises, or sauces.
  • Evaporation Method: If you are sautéing the mushrooms, you can add the liquid to the pan and let it evaporate, leaving behind an intense mushroom broth that coats the mushrooms.
  • Freezing: The mushroom liquid can be frozen for up to 3 months and used later in cooking.

Rehydrated mushrooms are a versatile ingredient that can enhance the flavour and texture of your dishes. Remember to cook them thoroughly and experiment with different cooking methods to find what works best for your taste preferences and specific recipes.
