Shiitake Drying: Techniques And Benefits

Dried shiitake mushrooms are a staple in Asian cooking, particularly in East Asian dishes like Chinese and Japanese soups, dumplings, and stir-fries. They are often used to amplify the umami flavour in vegetarian dishes. Shiitake mushrooms are typically sold dried in whole or sliced forms, with the former being preferred for its richer taste. When selecting dried shiitake mushrooms, it is recommended to choose those with thick caps and numerous cracks, which are indicative of higher quality and more flavour. The price of dried shiitake mushrooms can vary, with premium ones being quite expensive, especially those cultivated using traditional methods and natural materials. Drying methods can include sun-drying, drying with hot air, or using far infrared rays to reduce moisture content. Rehydrating dried shiitake mushrooms is an important step before cooking, and it involves soaking them in water, with some recipes suggesting lower temperatures for enhanced umami flavour. The mushroom soaking liquid can also be used as a flavourful ingredient in dishes.

How to rehydrate dried shiitake mushrooms

Dried shiitake mushrooms are a great ingredient to have on hand as they can be used in a variety of dishes and have a long shelf life. When rehydrated, they can be used in place of fresh shiitake mushrooms and have a deeper flavour. Here is a step-by-step guide on how to rehydrate dried shiitake mushrooms:

• Clean the dried shiitake mushrooms by rinsing them with water and brushing off any dust.
• Place the cleaned mushrooms in a container and cover them with water. The water level should be high enough to completely submerge the mushrooms.
• For the best flavour and texture, it is recommended to rehydrate the mushrooms slowly in the refrigerator for at least 6 hours or overnight. The water temperature should be less than 10°C for the best results.
• To reduce the soaking time, you can remove the stems after an hour of soaking and then continue soaking the caps for another hour or until soft.
• To test if the mushrooms are ready, squeeze the stems to ensure they are soft and rehydrated to the core.
• Once the mushrooms are rehydrated, remove them from the water and squeeze out the excess liquid.
• Trim off and discard the tough stems, and the caps are now ready to be used in your desired recipe.

It is important to note that the mushroom soaking liquid can be used as a flavour enhancer in various dishes, such as soups, sauces, or broths. Do not discard it! The liquid can be frozen for future use if needed.

Additionally, while some sources recommend using hot water for rehydrating the mushrooms, others suggest that this can result in a chewy texture and a loss of flavour. It is generally recommended to use cold water and allow for a longer soaking time to achieve the best results.

Uses of the mushroom soaking liquid

The liquid used for soaking dried shiitake mushrooms can be saved and has many culinary uses. It is particularly good for adding umami flavour to vegetarian dishes, such as roasted kabocha squash dumplings. It can also be added to canned chicken broth to enhance the flavour of a pot of chicken and shiitake mushroom rice.

The mushroom soaking water can be frozen for future use in stocks, soups, stews, or bolognese. It can also be used as a substitute for chicken stock in recipes, such as when making steamed dumplings or stir-fried vegetables.

The soaking liquid can also be used as a base for sauces. For example, the strained liquid from soaking the mushrooms can be combined with dark soy sauce and Chinese rice wine to make an oyster-flavoured sauce.

To maximise the umami flavour of the mushroom soaking liquid, it is recommended to rehydrate dried shiitake mushrooms in water at a low temperature of 10°C or lower in a refrigerator for at least 6 hours or overnight. This increases the amount of Guanylate, an Umami component unique to dried shiitake, which can give a bitter taste if its concentration is too high.
