Kombu dashi

Kombu Dashi (Japanese Kelp Stock)

Kombu dashi is a simple, plant-based Japanese stock made by soaking dried kelp in water. Full of clean umami flavor, it’s the perfect base for miso soup, noodle broth, or simmered dishes.

Ingredients
  

  • 1 piece dried kombu (about 10 cm / 4 inches long)
  • 500 ml water

Instructions
 

  • Gently wipe the kombu with a dry or lightly damp cloth to remove excess white powder (don’t rinse it — the powder is full of umami!).
  • Place the kombu in a pot or bowl with 500 ml of cold water. Let it soak for at least 30 minutes, or up to 2–3 hours. For a deeper flavor, soak overnight in the fridge.
  • Transfer the kombu and water to a saucepan. Slowly heat over medium-low heat.
  • Just before the water starts to boil (you’ll see small bubbles), remove the kombu. Do not boil it — this helps avoid bitterness.
  • Use immediately as your soup base, or let it cool and store in the fridge for up to 3 days.

Notes

Notes:
  • You can reuse the kombu once to make a second, lighter dashi (called niban dashi).
  • Kombu dashi freezes well in small portions (ice cube trays or jars).
  • Great as a base for miso soup, noodle soup, or simmered vegetables.
