Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Provide a mild, sweet body and bulk to the soup as they soften.
- Carrots
- Add natural sweetness and color while softening during the long simmer.
- Onions
- Build savory depth as they soften and brown lightly in the butter.
- Butter
- Carries the flavor of the vegetables and adds richness to the frying base.
- Celery
- Contributes savory aroma and a fresh, herbal backbone to the broth.
- Leeks
- Add a gentle, mild onion sweetness that deepens during frying and simmering.
The step that matters
Skimming off scum during the 3-hour simmer. Foam and impurities rise to the surface as the soup simmers. Skimming them off keeps the broth clear and free of bitter, off-flavors.
