Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Soften and add sweetness and body to the soup's vegetable base.
- Carrots
- Add natural sweetness and body as they soften during frying and simmering.
- Onions
- Build savory depth as they fry gently in butter until light yellow.
- Butter
- Carries the frying flavor and adds richness to the vegetable base.
- Celery
- Contributes aromatic, savory flavor as it softens in the pot.
- Leeks
- Add a mild onion-like sweetness that deepens the broth.
The step that matters
Skimming during the simmer. Scum rising from the simmering vegetables can cloud the broth and carry bitter or off flavors. Skimming it off keeps the soup clear and clean-tasting over the long 3-hour cook.
