Miso Soup (fish stock)
Yield: 1 quart/liter
 
Ingredients
  • 4 cups/1L filtered water
  • 4 grams (2" by 5" or 10 square inches) kombu (dried kelp)
  • 5 grams (about ½ cup, 125ml) katsuoboshi (bonito flakes)
  • 3 Tbsp./45 ml red miso
  • 2 scallions
  • 20 grams enoki mushrooms
Instructions
  1. Scrub kombu lightly under cool water to remove debris (pollution or small sea creatures).
  2. Add kombu to water in a pot and let soak for about 15 minutes.
Prep Veg
  1. Cut scallions into ⅛" slices.
  2. Trim dirt off enoki mushrooms then cut into 1" pieces.
Back to Broth
  1. Turn pot on medium-high heat. Right before the water starts to boil (bubbles starting to break around the edge of the pot), remove kombu and scatter the katsuobushi over the surface of the water. Reserve kombu to make niban dashi (second broth) or compost or discard if not desired.
  2. Let broth return to boil, then turn off heat and let sit 5 minutes.
  3. The flakes will have sunk to the bottom of the pot. Strain the stock through a tight mesh strainer. You now have dashi.
  4. Ladle 1 cup dashi into a small bowl. Let cool slightly, then add miso and whisk until smooth.
  5. Add the miso mixture back to the dashi and whisk to combine. Return to a slight simmer, being careful not to boil the mixture.
  6. Add scallions and mushrooms and cook for another minute.
  7. Remove from heat, ladle into soup bowls and serve immediately.
