Don’t throw out the kombu and katsuobushi when you are done - you can use it again for a less intense but still flavour-and-umami-ful dashi, called niban dashi (up next in the list).
Uses: miso soup, oyakodon (chicken and egg rice bowl), oden (fish cakes), ramen broth
2. Niban dashi (the second dashi)
After the primary dashi comes the second brew dashi, called niban dashi. As the name suggests, this is simply made from the once-boiled kombu and katsuobushi that gets a second life in a milder flavoured dashi.
How to make niban dashi
- Add the saved ingredients to cold water and bring to a boil
- Remove the kombu just as the water starts boiling and allow the katsuobushi to cook for a further 4 minutes
- Turn off the heat and strain
Uses: use this milder dashi where a recipe doesn’t specify an ichiban or awase dashi, but can still benefit from added umami notes. Perfect for stews, marinades, sauces and vegetable dishes where dashi is more of a background component.
3. Kombu dashi
A very simple dashi made just with kombu (dried kelp), this dashi is a vegetarian and vegan friendly stock with a mild taste. Kombu is high in glutamic acid, an amino acid that gives foods their umami taste. (In fact, the word ‘umami’ originated from the flavour of kombu dashi, identified by the Japanese chemist Kikunae Ikeda in 1908.)
Uses: kombu dashi is great in Japanese dishes that contain seafood, such as clam soup; also for shabu shabu (Japanese hot pot).
4. Shiitake dashi
Shiitake dashi is also made with a single ingredient, in this case, shiitake mushrooms. Any good Japanese pantry should have a bag of dried shiitake mushrooms ready to go (they’re also a common ingredient in Chinese and Korean cooking).
Vegetarian and vegan friendly, shiitake dashi is made by simply rehydrating the dried mushrooms in cold water for a few hours, or overnight. The soaking liquid is used as the stock, and the hydrated mushrooms can be sliced or chopped to use in the dish you wish to create.
Uses: shiitake dashi can be combined with other stronger dashi stocks. Used for chawanmushi (steamed savoury egg custard), stir-fries, steamed fish and vegetable dishes, udon noodle soup
