Ingredients
Quantities are shown as originally provided.
- 4 cups filtered cold water or chicken broth
- 1 piece kombu seaweed (4-inch strip)
- 3 tbsp miso paste (white, red, or mixed)
- 6 oz firm or silken tofu, cubed
- 1 cup daikon radish, thinly sliced

- 1 tbsp sake (optional)
- 1 tbsp grated ginger (optional)
- 1/4 shiitake mushrooms
- 1/4 white onion, thinly sliced
- 1/2 Carrot, thinly sliced
Instructions
- 1
Place the kombu in cold water and let it sit for 5 minutes while you prepare the other ingredients. This gentle extraction prevents bitterness that boiling would create. The kombu should start releasing its flavour and essence. The water will turn slightly golden.

Pro tip: Score the kombu with a knife before soaking to release more flavour compounds. For dried kombu, break it apart into smaller pieces first. Alternatively, use scissors to cut the pieces into smaller sizes after cooking.

Gently warm the kombu water over medium-low heat until it's steaming but not bubbling. Remove the kombu piece. You can reserve it for a second, lighter dashi or chop it up and add it back to your soup for extra texture.

Here's where many home cooks go wrong: never add miso paste directly to hot liquid. Instead, ladle about ½ cup of the warm dashi into a small bowl. Whisk in the miso paste until completely smooth and lump-free. This tempering prevents the miso from clumping and ensures even distribution.

Return the smooth miso mixture to your pot and stir gently.

Add sliced daikon and any harder vegetables, such as mushrooms or carrots. If using sliced pork, add it now and simmer for 3-4 minutes, until the pork is cooked through and the daikon is tender but still has a slight bite.

Add cubed tofu and any delicate ingredients, such as wakame, nori, or enoki mushrooms, in the final minute - just long enough to warm through without breaking apart.

Remove from heat and stir in chopped green onion whites. Taste and adjust. Add more miso for saltiness, a splash of sake for sweetness, or grated ginger for warmth.

Ladle into bowls and garnish with green onion tops and any additional seaweed or sesame seeds, as desired.
