Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fats the pot and carries the aromatics, adding richness and helping the vegetables soften and brown lightly.
- Turnips
- Provide body and a mild, slightly peppery flavor that deepens during the long simmer.
- Carrots
- Add natural sweetness and color to the broth as they soften.
- Onions
- Build savory depth as they fry and release sugars into the base.
- Leeks
- Contribute a mild onion-like sweetness and silky texture to the soup.
- Celery
- Adds savory, herbal aroma and a subtle salty backbone to the broth.
The step that matters
Skim off the scum while simmering. Scum is coagulated proteins and impurities that rise to the surface. Removing it keeps the broth clear and free of bitter, off flavors during the long simmer.
Swap the clove
