The Mise en Place

The Protein (0/1)
The Pantry (0/5)
Dashi tastes bitter.
Do not boil the kombu. Remove it as soon as the water simmers.
Miso soup tastes too salty.
Use less miso paste or a milder variety.
Chef's Notes
Gently stir in miso at the end to preserve its delicate flavor and probiotics. Don't boil after adding miso.
Garnish with thinly sliced scallions, a sprinkle of sesame seeds, or a few drops of chili oil for added flavor.
Prepare the dashi base and chop all vegetables ahead of time. Store separately and assemble just before serving.
The Method
SOAK
Prep aheadPlace kombu (4 inches) in a pot with 8 cups of water (8 cups) and let it soak for at least 30 minutes. This helps to soften the kombu and release its umami.
Bitter extraction: Do not boil the kombu, as high heat releases mucilaginous, bitter compounds.
Kombu is softened and submerged in water.
HEAT
Bring the water (8 cups) with the kombu (4 inches) to a gentle simmer over medium heat. Do not boil.
Boiling ruins flavor: Boiling the kombu releases mucilaginous slime and bitter tannins that ruin the dashi.
Water is gently simmering, with small bubbles appearing.
SIMMER
Simmer for 10 minutes, then remove the kombu (4 inches). Discard the kombu or save it for another use.
Over-steeping: Leaving the kombu in too long results in a bitter, astringent broth.
Kombu has been simmered for 10 minutes and removed from the pot.
ADD
Add the katsuobushi (2 cups) to the pot and simmer for 1 minute. Then, turn off the heat and let it steep for 5 minutes.
Avoid bitterness: Over-steeping or pressing the flakes will extract unwanted tannins and bitterness into the broth.
Katsuobushi has been added, simmered for 1 minute, and is steeping off the heat.
STRAIN
Strain the dashi through a fine-mesh sieve lined with cheesecloth. Discard the katsuobushi (2 cups).
Cloudy broth: Forcing the liquid through the cheesecloth will push sediment into your clear dashi.
Dashi has been strained through cheesecloth and katsuobushi is discarded.
RETURN
Return the dashi to the pot and gently warm it over low heat. Do not boil.
Boiling ruins flavor: Boiling the dashi after straining releases bitter, astringent compounds from the kombu and katsuobushi.
Dashi is back in the pot and warming gently.
DISSOLVE
In a small bowl, whisk a small amount of the warm dashi into the miso paste (4 tbsp) until smooth. This prevents clumping.
Grainy texture: Failing to fully dissolve the miso will leave gritty, concentrated pockets of paste in your final soup.
Miso paste is dissolved into a smooth mixture with a small amount of dashi.
STIR
Gently stir the miso mixture into the warm dashi in the pot. Do not boil after adding the miso, as this can affect its flavor and nutritional value.
Boiling destroys flavor: High heat kills the delicate aromatics and beneficial probiotics in the miso.
Miso mixture is fully incorporated into the dashi.
ADD
Add the cubed tofu (1 block) and rehydrated wakame seaweed (¼ cups) to the soup.
Tofu breakage: Stirring too vigorously will crumble the soft tofu cubes into the broth.
Tofu and wakame seaweed have been added to the soup.
GARNISH
Garnish with thinly sliced green onions (2 stalks) and serve immediately.
Soggy garnish: Do not stir the onions into the hot soup too early, or they will lose their color and texture.
Soup is garnished with green onions and ready to serve.
