Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main vegetable flavor and body as it softens in the broth.
- Butter
- Adds fat and richness, and helps the vegetables soften while steaming.
- Raw rice
- Thickens the soup as its starch releases during the long simmer.
- Tomatoes
- Adds acidity and fresh flavor that balances the vegetables and broth.
- Broth
- Forms the liquid base that carries the flavor of the whole soup.
The step that matters
Steaming the celery, green pepper, and butter. Covering the pan and steaming gently softens the vegetables in their own moisture and butter without browning them, so they blend into a smooth, mild base rather than a toasted one.
