Ingredients
Quantities are shown as originally provided.
- 2 1/4 cups water (cold)
- 2.85 oz tofu (soft or silken kind)
- 1/3 cup bonito flakes ((aka smoked skipjack tuna flakes))
- 2 tbsp yellow miso paste (reduced-sodium kind)
- 4 pieces kombu ((aka dried kelp))
- 0.10 oz wakame (dried seaweed)
- 1/2 green onion (finely chopped as an optional garnish)
Instructions
- 1
Carefully remove soft tofu from packaging and strain excess liquids (see blog post under "Expert Tips" to smoothly remove the soft tofu if guidance is needed).
- 2
Then slice tofu into small cubes with a sharp knife, about 1.5 cm x 1.5 cm each. Tip: Do not cut the tofu into large cubes as this doesn't taste as great in the miso soup.

Next in a small pot, add cold water, dried kelp and bonito flakes. Then cover and bring to boil on medium-high heat, uncovered.
- 4
As soon as it boils, only remove kelp to prevent the broth from becoming bitter in taste.
- 5
Then over very low heat, cover and simmer the broth for 5 minutes. Meanwhile, place a clean paper towel into a fine sieve and rest it over a large measuring cup or bowl.
- 6
Uncover and strain out the broth through the paper towel and fine sieve. Do not strain the broth without a paper towel or a fine sieve or it won't catch all the flakes. Pour this homemade dashi broth back into the pot.
- 7
On medium heat, mix the miso paste into the dashi broth until combined with a whisk to break down the paste more quickly.

Stir in dried wakame seaweed and allow it to expand. Then gently add diced tofu. Finally serve and garnish with green onions and enjoy!
