Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Give the soup its earthy, slightly sweet vegetable body as they soften during simmering.
- Carrots
- Add natural sweetness and body to the broth as they cook down.
- Onions
- Build savory depth and sweetness when fried gently in butter before the water is added.
- Leeks
- Contribute a mild onion-like flavour and soft texture to the broth.
- Butter
- Carries the aromatics and vegetables in the pot, adding richness and helping them soften and colour lightly.
The step that matters
Skimming off any scum during the 3-hour simmer. Foam and impurities rise to the surface as the broth simmers. Skimming them off keeps the soup clear and free of bitter or off flavours, which would otherwise be stirred back in.
