Citric Acid Free Classic Dashi
This deeply savory Japanese stock is built on just three ingredients — cold water, kombu, and bonito flakes — making it a naturally clean, additive-free foundation for so many dishes. For anyone avoiding citric acid, packaged broths and bouillons can be a minefield of hidden preservatives and flavor enhancers, but this one sidesteps all of that entirely. The technique is all about patience and gentle heat: the kombu is coaxed slowly through warm water to release its umami without turning bitter, and the bonito flakes steep off the heat so the broth stays delicate and clear. Scoring the kombu before soaking is a small step that makes a real difference, helping the seaweed release its full depth of flavor into the liquid. The result is a silky, golden broth with that unmistakable savory quality that makes miso soup, noodle dishes, and simmered vegetables taste so much more alive. It comes together with minimal effort and keeps in the fridge for a few days, so you can make a batch and reach for it all week long.

4 servings
- 4 cups cold water
- 1 oz (about 15–20 g) kombu
- 1 oz (about 1 packed cup) katsuobushi (bonito flakes)
Instructions
- 1
Use kitchen scissors or a knife to score the kombu with a few shallow cuts along its surface, then place it in a medium saucepan with the cold water. Let it soak for 30 minutes, until the kombu has softened and the water has taken on a faint golden tint.

Set the saucepan over medium-low heat and warm the kombu and water slowly, until small bubbles begin to form at the bottom of the pan and the water reaches about 140–150°F (60–65°C) — just below a simmer. This should take about 10 minutes. Do not let the water boil.
