Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mixed vegetables
- Provide the main body, flavor, and bulk of the soup once cooked and sieved.
- Haricot beans
- Add body and starch, helping the soup thicken when rubbed through a sieve.
- Butter
- Adds richness and fat, carrying flavor and giving the soup a smooth mouthfeel.
The step that matters
Boil until the vegetables are very soft. Vegetables must be fully softened so they break down easily when rubbed through a sieve. Undercooked pieces stay fibrous and leave a grainy, less smooth texture.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, leek, celery, butter, beans, sugar):
- Parsnipfits better
- Beetrootfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against carrot, turnip, leek, celery, butter, beans, sugar. Candidates are from the same food group and used in at least 100 recipes.
