Kombu dashi is a vegetarian base stock built on the subtle oceanic umami of dried kelp. Cold-steeping followed by a slow, low heat extraction avoids bitterness and cloudiness. Use it as a foundation for miso soup, simmered dishes, and clear broths.
Ingredients
- 1 piece dried kombu (about 4 inches square)
- 2 1/2 cups cold water
Method
-
Wipe the surface of the kombu lightly with a dry cloth if dusty, but leave the white mineral bloom intact since it contributes flavor.
-
Place the kombu in a 6-quart saucepan with the cold water and let it soak, covered, at room temperature.
-
Set the saucepan over low heat and warm gently, uncovered, watching for small bubbles to form around the kombu.
-
Just before the water reaches a simmer, remove the kombu with tongs and discard or reserve for another use; do not let the dashi boil, as boiling makes the stock bitter and cloudy.
-
Let the dashi cool slightly, then strain through a fine-mesh sieve into a clean container.
-
Use the kombu dashi immediately, or refrigerate in an airtight container for up to 3 days.
