Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Carrots
Provide sweetness, colour and body as the main root vegetable in the soup.
Turnips
Add a mild, slightly peppery flavour and firm texture that holds up to cooking.
Leeks
Contribute a gentle onion-like sweetness and aroma to the broth.
Butter
Adds fat and helps fry the root vegetables, carrying flavour and browning them gently.
Broth
Forms the liquid base that moistens and carries the vegetables into the finished soup.

The step that matters

Frying or stewing the root vegetables in butter. Cooking the roots gently in a little butter softens them evenly and builds flavour without browning them too much. Too much heat can scorch the butter and make the soup taste bitter, while too little leaves the roots firm and raw-tasting.

Swap the cabbage

How well each one fits the dish's main ingredients (carrot, turnip, leek, onion, celery, parsley, butter):

  1. Parsnipfits better
  2. Chivefits better
  3. Shallotfits better
  4. Cabbagethe original

Fit is the average pairing score against carrot, turnip, leek, onion, celery, parsley, butter. Candidates are from the same food group and used in at least 100 recipes.
