The Magic Of Rehydrating Mushrooms: A Quick Guide

Dried mushrooms are a handy and cost-effective way to add a burst of flavour to your dishes. They are often used in Asian and European cuisines and can be easily rehydrated. The process of rehydration involves soaking the dried mushrooms in water until they are tender. While there are varying opinions on the temperature of the water and the duration of soaking, room temperature or warm water for a few hours is generally recommended. The resulting broth from soaking the mushrooms can be used in recipes to enhance the flavour. However, it is important to note that rehydration is not the same as cooking, and rehydrated mushrooms should be thoroughly cooked before consumption.

Characteristics and Values Table for Rehydrating Mushrooms

Soak in warm water for a few hours

Rehydrating dried mushrooms is simple: just soak them in warm water for a few hours. The amount of water you use and the length of time you soak the mushrooms will depend on the type and size of the mushroom. For example, a dried laetiporus sp. (chicken of the woods) mushroom the size of a dinner plate will take longer to rehydrate than smaller varieties.

Before you start, it's important to clean your mushrooms. Some people recommend scrubbing reconstituted mushrooms with salt and flour until the water runs clear. However, this may be unnecessary if you've purchased your mushrooms from a store, as they will have already been cleaned.

To rehydrate your mushrooms, place them in a bowl and cover them with warm water. You can use hot water if you're in a hurry, but this will extract more of the mushrooms' flavour. To ensure that all the mushrooms are fully submerged, place a smaller bowl inside the larger bowl, weighing it down so that it pushes the mushrooms under the water.

After a few hours, your mushrooms should be tender and ready to use. If you're not in a rush, you can even leave them to soak overnight. Just remember to remove the mushrooms from the water when they're rehydrated to your liking, as leaving them for too long can make them rubbery and tasteless.

Use hot water if you're in a hurry

If you're short on time, you can use hot water to rehydrate your mushrooms. This method is faster than using room-temperature or cold water, but it does come with a trade-off: more of the mushrooms' flavour will be extracted into the soaking water.

To use this method, simply place your mushrooms in a bowl and cover them with hot water. You only need to add enough water to submerge the mushrooms. Leave the mushrooms to soak for 20 minutes to an hour. If you're in a real hurry, even a few minutes of soaking will help.

Thickly sliced or capped mushrooms are the best candidates for rehydration with hot water. If your mushrooms are thinly sliced, it's better to use room-temperature water, as hot water may overcook them.

The type and size of mushroom will also affect the rehydration time. Smaller mushrooms, such as shiitake, will rehydrate more quickly than larger varieties like chicken of the woods.

After your mushrooms have soaked, you may want to rinse them under running water to remove any residual grit. Be aware that this may wash away some of the flavour. You can taste one of the mushrooms before adding it to your dish to see if it needs rinsing.

Rinse mushrooms after soaking to remove grit

When rehydrating dried mushrooms, it is important to consider the presence of grit. Dried mushrooms are often gritty, and even a tiny amount of grit can ruin a dish. To avoid this, it is recommended that you rinse your mushrooms after soaking them.

Firstly, start by soaking the mushrooms in room-temperature water. If you are in a hurry, you can use warm or hot water, but be aware that this will extract more of the mushrooms' flavour into the soaking water. Thickly sliced or capped mushrooms can be soaked in hot water.

Once the mushrooms have softened, they should be rinsed under running water to remove any residual grit. It is a common myth that rinsing mushrooms will wash away their flavour, but this is not true. Mushrooms are mostly water, and a little extra water will not change their flavour or texture. After rinsing, taste a mushroom to be sure that its flavour is satisfactory, and then dry the mushrooms thoroughly. You can use paper towels or a clean kitchen towel to pat them dry, or use a salad spinner to remove moisture from the gills.

If your mushrooms are particularly dirty, you may wish to soak them in lightly salted water. The salt will help to evict any tiny creatures, and you can then rinse the mushrooms in cool water before patting them dry.

Use the mushroom soaking liquid in recipes

The liquid used for soaking dried mushrooms is full of umami flavour and nutrition. This liquid can be used in a variety of ways when cooking. Firstly, it can be frozen and saved for future use in stocks, soups, stews or bolognese. Secondly, it can be used immediately as a broth for cooking rice or noodles.

The mushroom soaking liquid can also be used in place of chicken broth in recipes. For example, in a stir-fry, the mushroom liquid can be used as a base for an oyster-flavoured sauce, which also includes dark soy sauce and Chinese rice wine. In another stir-fry recipe, the mushroom liquid can be used in place of chicken broth and combined with Chinese greens. The liquid can also be used to braise vegetables, preventing them from drying out.

The mushroom soaking liquid can also be used to make a vegan-friendly substitute for chicken stock. It can be used to make a soup, for example, a delicious steamed egg with seafood. It can also be used to make a soup with the cut mushroom stems, which can be frozen until needed.

Cook mushrooms thoroughly after rehydrating

Dried mushrooms are a versatile and flavourful ingredient used in cooking. They are often used in Asian and European cuisines. They are also a great way to add a savoury, umami taste to your dishes. However, it is important to remember that dried mushrooms must be thoroughly cooked after rehydration. This is because mushrooms contain chitin, a substance that human stomachs cannot digest.

To cook mushrooms after rehydrating, you can try stir-frying them in a wok with some neutral oil and soy sauce. You can also cook them in butter. Mushrooms pair well with a bit of fat and salt. You can also add them to soups, stews, sauces, pâtés, and gratins.

When cooking with dried mushrooms, it is important to first rehydrate them. To do this, place the mushrooms in a bowl and add room temperature or tepid water. You can use hot water if you are in a hurry, but this will extract more of the mushroom's flavour into the soaking water. Make sure all the mushrooms are submerged—some mushrooms will float, so you may need to place a smaller bowl inside the bowl to keep them under the water. Thickly sliced or capped mushrooms will take longer to rehydrate, so you may need to leave them for up to 20 minutes.

Once the mushrooms are plump, remove them from the water and squeeze out the excess liquid. You can then chop, slice, or blend them as needed for your recipe. It is recommended that you rinse the mushrooms under running water to remove any residual grit. You can then taste a mushroom to check for grittiness and, if happy, add them to your dish.
