What You'll Learn
Soaking time: 20-30 minutes, longer for thicker mushrooms
The soaking time for dried mushrooms depends on the thickness of the caps. Thinly sliced mushrooms will be rehydrated in 20 to 30 minutes, while thicker and whole cap mushrooms may take a little longer. To speed up the process, you can soak them in hot water, although this may affect the mushrooms' flavour. Cold water is the best way to rehydrate dried mushrooms as it helps them retain their flavour.
If you are in a hurry, you can soak the mushrooms in hot water for 15 to 30 minutes, but this is not ideal. The liquid from soaking the mushrooms can be used to enhance the flavour of a soup or braising liquid or it can be added to stir-fried vegetables to prevent them from drying out. It can also be used as a vegetarian/vegan substitute for chicken stock in recipes.
If you are rehydrating Chinese dried mushrooms, or shiitake mushrooms, you should soak them in warm water for 20 to 30 minutes or until softened. The warm water temperature should be roughly the same as bathwater. To help them soften faster, you can flip them over once or twice during soaking.
If you are using a French press, fill it with your dried mushrooms and cover them with hot water for 20 minutes to an hour. When the mushrooms have softened, slowly push down on the plunger like you are making coffee. You can save the liquid for stocks and braises or discard it.

Water temperature: hot water reduces soaking time but affects flavour
The temperature of the water used for rehydrating dried mushrooms is a key factor in the process. Using hot water reduces the time required for rehydration but may negatively impact the flavour of the mushrooms and the consistency of their texture.
Hot water can reduce the soaking time for dried mushrooms to as little as 10 minutes for thin varieties like wood ears and black fungus, and 15 to 30 minutes for larger, denser mushrooms like shiitake. This is because the higher water temperature speeds up the rate at which the mushrooms absorb water and swell. However, hot water can also affect the flavour and texture of the rehydrated mushrooms.
When mushrooms are soaked in very hot water, they can become partially cooked, resulting in a chewy, tough, and inconsistently textured mushroom. The hot water can also extract more of the mushroom's flavour, resulting in a less aromatic mushroom and more intensely flavoured soaking water. This can be advantageous if the mushroom soaking water is to be used as a broth or stock, but it may be undesirable if the goal is to retain as much flavour as possible in the mushrooms themselves.
For this reason, some sources recommend using room temperature or cold water to rehydrate dried mushrooms. This allows the mushrooms to absorb water and rehydrate at a slower, more natural pace, resulting in a more consistent texture and better flavour retention in the mushrooms. However, this method can take significantly longer, with soaking times ranging from 20 minutes to 8 hours, depending on the thickness and variety of the mushrooms.
Ultimately, the decision of whether to use hot, warm, or cold water for rehydrating dried mushrooms depends on the cook's priorities. If time is a factor and a shorter soaking time is desired, then hot water is a good option, but if flavour retention and texture consistency are more important, then room temperature or cold water may be preferable.

Use a French press to keep mushrooms submerged
Dried mushrooms are a great way to enjoy your favourite fungi year-round. They can be stored in your pantry for years, ready to be rehydrated and used in soups, stews, and broths. While there are several ways to rehydrate mushrooms, a French press is a handy tool to keep them submerged.
First, rinse the dried mushrooms with cold water to remove any dirt or grit. Then, fill a large French press with the mushrooms and cover them with hot water. The amount of time required for soaking depends on the type of mushroom and its thickness. Thin mushrooms like wood ears and black fungus will rehydrate in about 10 minutes, while larger and denser mushrooms like shiitake will take 20 to 30 minutes.
During the soaking process, you can slowly push down on the plunger of the French press to keep the mushrooms fully submerged. This ensures that they are evenly rehydrated. Once the mushrooms have softened, you can press down on the plunger to extract even more flavour from them.
The liquid that remains after soaking the mushrooms can be used as a flavourful addition to stocks, soups, or braises. Alternatively, you can discard it if you prefer. Now you have plump, rehydrated mushrooms ready to be used in your favourite recipes!

Rinse dried mushrooms before soaking
Rinsing dried mushrooms before soaking them is a good idea to get rid of any dust or dirt. Some mushrooms can have a lot of grit on them, and rinsing them first can help remove most of it. Using cold water for the rinse is recommended, as hot water may wash away some of the flavour.
After rinsing, the mushrooms should be soaked in water. The temperature of the water depends on the type of mushroom and how quickly you want to rehydrate them. Thinly sliced mushrooms will rehydrate faster than thick and whole-cap mushrooms. Hot water will rehydrate mushrooms faster, but it may affect their flavour. If you're not in a hurry, room temperature or lukewarm water is recommended.
The soaking time for mushrooms varies depending on their size and thickness. Thinly sliced mushrooms will be rehydrated in 20 to 30 minutes, while thicker and whole-cap mushrooms may take longer. Thin mushrooms like wood ears and black fungus will rehydrate fully in about 10 minutes, while dried shiitake mushrooms will take 20 to 30 minutes.
It's important to use a bowl that is large and deep enough so that the mushrooms have room to swell. You don't want to overcrowd them, so make sure each piece is completely covered in water. To help them soften faster, you can flip them over once or twice during soaking.
Once the mushrooms are rehydrated, they should be lifted from the water and gently squeezed to remove excess liquid. You can then taste a mushroom to check for any grittiness. If they still feel gritty, give them a quick rinse under running water. However, some people believe that rinsing the mushrooms after soaking washes away their flavour, so this step is optional.

Use the soaking liquid in stocks, soups, and braises
The liquid used for rehydrating dried mushrooms can be used in stocks, soups, and braises. This liquid is full of flavour and can be used as a vegetarian/vegan substitute for chicken stock. It can also be used to make sauces and cook rice.
When using the liquid for stocks, it can be added to risottos, soups, stews, casseroles, and more. The liquid can be used as a base for soups and stews, adding umami to the dish. It can also be used in braises, sauces, and gravies. To make a mushroom stock, simply simmer mushrooms and vegetables in water. For a more neutral stock, skip the herbs, spices, and seasonings, and add them later when you plan to consume the stock.
The mushroom soaking liquid can be added to braises, such as in a dish with tofu and vegetables braised in soy sauce, stock, sugar, and sesame oil. It can also be used in stir-fries, replacing the chicken broth in a recipe with the strained liquid from soaking the mushrooms.
When using the liquid for soups, it is important to strain the liquid through a fine mesh or cheesecloth to catch any dirt or rocks that may have slipped in with the mushrooms. The liquid can be added to hot and sour soup, vegetable beef barley soup, or any other soup of your choice.
