Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Provide the soup's base flavour and body as they soften during the long simmer.
- Carrots
- Add sweetness and colour to the soup as they cook down.
- Onions
- Build savoury depth when fried gently in butter before the water goes in.
- Butter
- Carries fat for frying the vegetables, adding richness and helping them brown lightly.
- Leeks
- Contribute a mild onion-like sweetness and softness to the broth.
- Celery
- Adds savoury, aromatic flavour to the broth as it simmers.
The step that matters
Frying the turnips, carrots, and onions until light yellow. Frying in butter first softens the vegetables and develops mild savoury flavour. Browning too far can turn the soup bitter, while skipping this step leaves a flatter taste.
