Ingredients
- 4 cups filtered water
- 10g dried kombu (kelp)
- 15g bonito flakes (katsuobushi)
- 3 tablespoons white miso paste (preferably shiro miso for its mild flavor)
- 1 teaspoon mirin (optional, for subtle sweetness)
- 1 teaspoon soy sauce (low sodium recommended)
- 1/2 teaspoon freshly grated ginger
- 2 scallions, thinly sliced
- 1/4 cup silken tofu, cubed
- 1 small cucumber, thinly sliced or julienned
- Fresh shiso leaves or microgreens for garnish
Instructions
- Prepare the dashi broth: place the kombu in a pot with 4 cups of filtered water and soak for 30 minutes to an hour. This slow infusion brings out deep umami flavors.
- Heat gently: Slowly warm the kombu-water mixture over medium heat, removing the kombu just before the water reaches a boil (about 60°C or 140°F). This avoids bitterness and preserves subtle flavors.
- Add bonito flakes: Stir in the bonito flakes, simmer for 2 minutes, then turn off the heat and let it steep for another 5 minutes.
- Strain the broth: Carefully strain out the bonito flakes and any solids using a fine sieve or cheesecloth. Let the dashi cool to room temperature, then chill in the refrigerator for at least 30 minutes.
- Mix the miso: In a small bowl, whisk together the white miso paste with 1/2 cup of chilled dashi until smooth. This ensures no lumps and a silky texture in the final soup.
- Combine all ingredients: Gently stir the miso mixture back into the chilled dashi. Add mirin, soy sauce, and freshly grated ginger, adjusting to your taste.
- Assemble the soup: Divide the cold miso dashi soup into serving bowls. Float cubes of silken tofu, cucumber slices, and scallions on top.
- Garnish and serve: add fresh shiso leaves or microgreens for a burst of color and fragrance. Serve immediately for the freshest experience.
Chef’s Notes & Tips for Success
- Ingredient Substitutions: If bonito flakes are unavailable, use dried shiitake mushrooms for a vegetarian dashi choice that offers a rich, earthy depth.
- Miso Varieties: While white miso imparts a delicate sweetness, red or mixed miso can add more intense, smoky notes-perfect for chillier evenings.
- make-Ahead: Prepare your dashi broth a day in advance to allow flavors to fully meld. Keep miso and delicate toppings separate until serving to maintain their texture and brightness.
- Chilling Tips: Avoid freezing miso dashi; chilling in the fridge preserves its velvety mouthfeel and complex aroma.
- Balancing Flavors: Taste before serving and adjust with a dash of soy sauce or a hint of citrus zest for a brighter finish.
Serving Suggestions and Seasonal Variations
