Dashi is a style of Japanese stock or broth that forms the base of many Japanese dishes, including the last miso soup you ate. While dashi is usually made with bonito flakes and kelp, it can also be made with mushrooms, particularly shiitake mushrooms, and kombu (an edible ocean plant). Mushroom dashi is a great option for those following a plant-based diet and can be made by simply combining dried shiitake mushrooms and kombu with water and allowing the ingredients to infuse overnight in the refrigerator.

Shiitake mushrooms are used to make dashi stock due to their high umami content when dried
Dashi is a style of Japanese stock or broth. It is an essential base for many Japanese dishes, including soups, rice dishes, and noodle bowls. Dashi can be made with a variety of ingredients, including chicken, fish, beef, and mushrooms. Mushroom dashi, or shiitake dashi, is a plant-based variety of dashi that is made by rehydrating dried shiitake mushrooms in water.
Shiitake mushrooms are a key ingredient in making dashi due to their high umami content when dried. Umami, meaning "pleasant savory taste" in Japanese, is one of the five basic taste groups, along with sweet, sour, salty, and bitter. It is found in foods that contain glutamate, and shiitake mushrooms are known for their high levels of glutamate-containing compounds like guanylic acid and glutamic acid.
Guanylic acid, the primary component of shiitake dashi, is created through the process of drying fresh shiitake mushrooms. When dried shiitake mushrooms are rehydrated in cold water, ribonucleic acid (RNA) is extracted and then converted to guanylic acid. This process is optimized in cold water at 41°F (5°C) and is hindered if the mushrooms are rehydrated with hot water or boiled. Therefore, it is crucial to use dried shiitake mushrooms and cold water when making shiitake dashi to maximize its umami flavor.
The extraction of umami components from shiitake mushrooms can be influenced by the preparation of the mushrooms. Sliced, dried shiitake mushrooms will yield enough umami flavor in about half the time compared to whole mushrooms, but the aroma extraction is less successful. To enhance the nutrient content of shiitake dashi, the dried mushrooms can be placed gill-side up in the sunlight for about two hours before rehydration, increasing the vitamin D2 content by approximately ten times.
Shiitake dashi is a versatile and flavorful stock that can be used in various dishes. It is simple to prepare, requiring only dried shiitake mushrooms and water, and it can be stored in the refrigerator for a few days or frozen for later use.

Dashi is a style of Japanese stock or broth
Shiitake mushrooms are used to make dashi because they have a high umami content when dried. Guanylic acid, the primary component of shiitake dashi, is created when fresh shiitake mushrooms are dried. This process results in the mushrooms containing over ten times the amount of guanylic acid compared to other mushrooms.
When making shiitake dashi, it is important not to use hot water or heat during the process, as this will prevent the extraction of ribonucleic acid (RNA), which is the precursor to guanylic acid.
Mushroom dashi can be used as a base for dozens of recipes, including soups, noodle dishes, and rice dishes. It can be used on its own or combined with other dashi, such as seafood dashi, to create unique flavours.
Mushroom dashi can be stored in an airtight container in the refrigerator for up to three days or frozen for up to a month. It is a versatile and flavourful ingredient that can enhance the taste of many dishes.

Dashi is easy to make and can be stored in the refrigerator for 2-3 days
Dashi is a Japanese stock or broth. It is an essential base for many Japanese dishes, such as soups, noodle bowls, and rice dishes. It is also used as a base for miso soup.
Mushroom dashi is a type of dashi made from dried shiitake mushrooms and kombu (edible kelp). It is a great option for those following a plant-based diet. The process of making mushroom dashi is simple and requires minimal effort and no cooking.
To make mushroom dashi, combine dried shiitake mushrooms and kombu in a bowl and cover with water. Leave the mixture to infuse overnight in the refrigerator. The longer the mixture infuses, the richer the flavour will be. After infusing, the kombu and shiitake can be removed, sliced, and cooked in a soup or another dish.
Once made, mushroom dashi can be stored in an airtight container in the refrigerator for 2-3 days. It can also be frozen for up to a month. This makes it a convenient option to have on hand, ready to be used as a base for a variety of dishes.

Dashi can be made with kombu (dry kelp) and dried shiitake mushrooms
Dashi is a style of Japanese stock or broth. It is an essential base for many Japanese dishes, including soups, noodle bowls, and rice dishes. Dashi can be made with kombu (dry kelp) and dried shiitake mushrooms.
To make kombu and shiitake mushroom dashi, combine the kombu and dried shiitake in a bowl and pour water over them. Leave the mixture in the refrigerator overnight to infuse. After infusing, remove the kombu and shiitake from the water, and your dashi is ready to use. The infused kombu and shiitake can be cooked with the dashi to add even more flavour.
It is important to note that the dashi-making process requires dried shiitake mushrooms, not fresh ones. This is because guanylic acid, the primary component of shiitake dashi, is created through the process of drying fresh shiitake mushrooms. When making dashi, it is also crucial to avoid using hot water or heat during the extraction process. Instead, dried shiitake mushrooms should be rehydrated in cold water in the refrigerator for around 10 hours to extract the maximum amount of flavour.
Shiitake dashi is one of the easiest dashi stocks to make and is a great option for those following a plant-based diet. It has a rich aroma and flavour and contains high levels of guanylic acid and glutamic acid, which are umami components that people find tasty.

Dried shiitake mushrooms should not be heated or rehydrated with hot water during the process of making dashi stock
Dashi is a Japanese stock or broth, often used as a base for soups, noodle dishes, and rice dishes. It is an essential component of Japanese cooking and can be made in a variety of ways, including with mushrooms.
Shiitake dashi, in particular, is a type of dashi stock made from dried shiitake mushrooms. It is one of the easiest types of dashi to make and is suitable for those following a plant-based diet. The process of drying fresh shiitake mushrooms creates guanylic acid, the primary component of shiitake dashi, which is why dried shiitake mushrooms, not fresh ones, are used to make this flavorful stock.
When making shiitake dashi, it is important not to heat the dried shiitake mushrooms and not to rehydrate them with hot water. This is because ribonucleic acid (RNA), which is present in the dried mushrooms, is most easily extracted in cold water at 41°F (5°C). When the mushrooms are rehydrated in hot water or boiled, the RNA breaks down and is converted to guanylic acid, but it is difficult to extract enough of it, resulting in a less flavorful stock. Therefore, it is recommended to rehydrate dried shiitake mushrooms in cold water in the refrigerator for a longer period, ideally for about 10 hours, to produce the best-tasting dashi.
Although it may take longer, preparing shiitake dashi in this way ensures that the maximum amount of flavor and aroma is extracted from the mushrooms. This method also allows for the extraction of the distinctive aroma of shiitake mushrooms, which contributes to the overall taste experience of the dish. By following these simple steps, anyone can create an authentic and delicious shiitake dashi at home.
