Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Browns the vegetables and adds richness and flavour to the broth.
- Carrots
- Add sweetness and colour, and hold their shape through the cooking time.
- White broth or consommé
- Forms the liquid base of the soup and carries the seasoning.
- Leek
- Adds a mild onion-like aroma and body to the broth.
The step that matters
Browning the vegetables in butter. Browning the shredded vegetables in butter develops savoury, toasted flavours through the Maillard reaction. Too little heat or crowding the pan steams them instead, leaving the soup flat and pale.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, celery, leek, cabbage, butter, pepper):
- Parsnipfits better
- Lettucefits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against carrot, turnip, celery, leek, cabbage, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
