Why it works: Tofu and miso share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 75 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Traditional Japanese Noodle Soup
Ingredients
Directions
Prepare the tofu
In a nonstick 10-inch skillet over medium-high heat, in hot vegetable oil, cook tofu, green onion, and ginger for 5 minutes or until golden brown.
Simmer the soup
In a 4-quart saucepan over high heat, heat 8 cups of water to a boil.
Add soup mix, noodles, carrot, red pepper, lemon peel, crushed red pepper, and tofu mixture.
Boil for a few minutes.
Reduce heat to a low simmer for 8 to 10 minutes.
Cook until veggies are tender and noodles are loose.
Then, stir in watercress until it wilts.
Serve immediately because the noodles will absorb the soup quickly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Firm tofu
- Browns in the hot oil to add golden color and a firm, chewy bite to the soup.
- Dried udon noodles
- Provide the chewy, starchy body of the soup and soak up broth as they sit.
- Miso soup mix
- Supplies the savory, salty base flavor that defines the soup.
- Carrot
- Softens during simmering, adding mild sweetness and color to the broth.
- Watercress
- Added at the end so it wilts gently, adding fresh, slightly peppery greens.
The step that matters
Serve immediately. Noodles keep absorbing broth as they sit, so the soup thickens and becomes soggy. Serving right after the final simmer keeps the noodles tender and the broth loose.
