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, mildly sweet body as they soften during the long simmer.
- Carrots
- Add natural sweetness and color, and thicken the broth as they break down.
- Onions
- Build savory depth through browning and release sweetness as they cook slowly.
- Butter
- Carries fat for frying the vegetables, adding richness and helping them brown lightly.
- Celery
- Contributes savory, aromatic flavor that underpins the broth.
- Leeks
- Add a mild onion-like sweetness and aroma to the broth.
The step that matters
Frying the vegetables until light yellow. Frying gently softens the vegetables and begins browning their natural sugars, building flavor before the water goes in. Frying too hot can scorch the butter and turn the soup bitter.
