Japanese Bonito Sauce is made with kombu dashi, dried bonito flakes, and seasonings. It is an essential dipping sauce for Japanese soba noodles, with its quality determined by the soy sauce and bonito used.
This is a concentrated home-use version, and should be diluted with water according to different needs. For soba dipping sauce, mix one part sauce with two parts water, then add chopped green onions and wasabi for an extra burst of flavor. Delicious!
