Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts to fry the vegetables and adds richness and flavor to the soup.
- Carrots
- Add sweetness and color, and hold their shape in the julienne cut.
- Turnips
- Add mild, slightly sweet flavor and body to the vegetable base.
- Celery
- Adds aromatic flavor and a crisp-tender texture to the soup.
- Onions
- Add savory depth and sweetness as they brown in the butter.
- Leeks
- Add a mild onion-like aroma and sweetness to the broth.
The step that matters
Frying the vegetables over low heat until nicely browned. Gentle heat browns the vegetables slowly, building sweet, savory flavor through browning reactions without scorching them. Too much heat burns the butter and sugars and makes the soup taste bitter.
