Nutrition Facts
Per 240 mL (1 cup)Chef’s Secret
For a quick, deeply umami "awase dashi," briefly soak kombu in cold water, heat gently, remove before boiling, then steep katsuobushi and strain immediately. Avoid boiling kombu to prevent sliminess.
Substitutions
Vegetable Broth (with mushroom/soy sauce)
1:1Best vegan and readily available option; add dried shiitake mushrooms for umami, soy sauce for depth.
Chicken Broth
1:1Provides a savory base, but lacks the distinct marine umami of dashi; good for some soups.
Clam Juice (diluted)
Offers a subtle marine flavor, but can be too strong if not diluted; suitable for seafood dishes.
MSG (Monosodium Glutamate)
Pure umami enhancer; use judiciously to boost the savory profile of a substitute broth.
Buying Guide
For convenience, choose instant dashi powder/granules. For authentic flavor, buy good quality kombu and katsuobushi.
