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

What each ingredient does

Carrots, turnips, parsnips, cabbage, celery, leeks, potatoes, onions
Form the body of the soup, providing bulk, texture and natural sweetness as they soften.
Butter
Adds fat and richness, carrying flavour through the vegetables as they stew.
Broth
Provides the liquid that cooks the vegetables through and forms the soup base.

The step that matters

Stewing the vegetables before adding the broth. Covering the vegetables and stewing them gently in butter draws out moisture and softens them slowly, concentrating flavour. Adding the broth too early would boil the vegetables instead, diluting that flavour.

Swap the onion

How well each one fits the dish's main ingredients (carrot, turnip, parsnip, cabbage, celery, leek, potato):

  1. Beetrootfits better
  2. Lettucefits better
  3. Jerusalem artichokefits better
  4. Onionthe original

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