    Japanese Seasoning Low Calorie Contains fish Contains seaweed

    In Japanese cuisine, dashi is one of the most used ingredients.  However, even though it is a basic in many Japanese dishes like miso soup, udon or eggrolls, most Japanese people don't make dashi from the scratch nowadays. Instead, many people use instant dashi powders or ready-made dashi liquids rather than homemade dashi.

    However, homemade dashi is; much more flavourful, has no artificial substances, and most importantly, it is easy to make.

    Expert's Tip

    If you want to make a rich, umami infused dashi, one of the most common dashi ingredients is katsuobushi or bonito flakes. Bonito flakes are packed with an intense savory taste, and its flavor pairs well with many Japanese dishes. It can also be used as a topping for Okinomiyaki, Yakisoba, Takoyaki, and many other Japanese dishes. You can even make homemade furikake with bonito flakes. Bonito flakes may be a little difficult to find in supermarkets overseas, so be sure to check out our site for 100%, made in Japan bonito flakes.


    Preparing the Kombu
    1) Preparing the Kombu

    Gently clean the dried kelp by wiping gently with a damp cloth. (Please try not to remove the white powdery parts of the dried kelp off because it is "umami." Also, please do not wash the dried kelp with water.) Put the dried kelp and 1 liter of water in a pot and soak the seaweed for at least 30 minutes to 1 hour (or ideally, overnight).

    Boiling the Kombu
    2) Boiling the Kombu

    Put the pot on the heat, and bring it to a near-boil over medium low heat. Skim the surface if you see any impurities. Just before boiling, take the dried kelp out to avoid dashi becoming slimy and bitter.

    Adding the Katsuobushi
    3) Adding the Katsuobushi

    Turn off the heat and let the dashi cool down slightly. After cooling down slightly, put the pot back on the heat.(You can choose to skip this step.) Put the dried bonito flakes into the pot and boil the mixture for about 2 minutes on low heat. Turn off the heat and leave it for about 5 minutes to 10 minutes to let the bonito flakes sink to the bottom.

    Preparing and Storing the Dashi Broth
    4) Preparing and Storing the Dashi Broth

    Take the bonito flakes (katsuobushi) out by straining the dashi with the kitchen paper or a clean woven cloth over a sieve. Now it's done. We have just made the dashi so called Ichiban dashi (the first brewed dashi).
