Why it works: Miso and seaweed work together. They rank in the top 4% of all ingredient pairs, and 18 recipes mention both. Both carry ethyl decanoate, which smells grape, waxy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Miso
- Provides salty, savoury depth and flavour to the broth.
- Tofu
- Adds soft texture and absorbs the surrounding broth flavour.
- Mushrooms
- Add savoury, earthy flavour and a tender chew to the soup.
The step that matters
Dissolve miso in water before adding it to the pot. Miso paste clumps when added straight to hot liquid. Dissolving it first in a little water spreads it evenly, so the broth tastes uniform. Keeping the soup just below a boil after adding miso helps preserve its delicate aroma.
Flavor stand-ins for the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (sesame, miso, tofu, mushroom, shrimp, seaweed):

Fit is the average pairing score against sesame, miso, tofu, mushroom, shrimp, seaweed. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
