Ingredients

  • 1 piecekombu seaweed, 4-inch piece (dried kelp)
  • 4 cupfiltered water
  • 1 cupbonito flakes (katsuobushi), loosely packed

Instructions

  1. Clean the kombu with a barely damp cloth to remove surface dust — resist the urge to rinse it under water, which would wash away the natural salts that give dashi its depth.
  2. Drop the kombu into a medium saucepan with the water and let it soak at room temperature for 30 minutes. This gentle extraction pulls out the glutamates without any harsh flavors.
    30 min
  3. Place the pot over medium-low heat and watch for tiny bubbles to appear around the kombu's edges — this signals the water is hot enough to release the seaweed's essence without bitterness.

  4. Lift out the kombu just before the water reaches a full boil. Leaving it in longer would turn your delicate stock into something murky and overpowering.
  5. Crank up the heat and bring the kombu-infused water to a vigorous boil, then scatter in all the bonito flakes at once — they'll dance and swirl as they hit the bubbling water.
  6. Kill the heat immediately and let the bonito flakes steep undisturbed for 3-5 minutes. The flakes will slowly sink as they release their smoky, oceanic flavor into the stock.

  7. Pour everything through a fine-mesh strainer lined with cheesecloth, pressing gently on the spent flakes to extract every last drop of this liquid gold.
