  • Once cooled, pour into a jar or sealable container and add your choice of dashi ingredients. (Classic: 3 g bonito flakes and 5 g dried kelp (kombu). Plant-based: 3 g dried shiitake mushroom(s) and 5 g dried kelp (kombu). Rich: 3 g bonito flakes, 5 g dried kelp (kombu) and 3 g dried sardines (niboshi))
    Seal the container and soak in the refrigerator overnight (at least 12 hours).

  • After 12 hours, remove the dashi ingredients. (If you used bonito flakes, I recommend using a fine mesh sieve to strain and squeeze them to prevent wasting any sauce.) Transfer to a sterilized container for storage and keep it in the fridge.
