Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Releases flavor and body into the broth as it simmers.
- Veal
- Adds gelatin-rich body and a delicate meaty flavor to the broth.
- Caramel
- Adds a deep amber color and a subtle bittersweet flavor to the soup.
- Poached eggs
- Add soft, rich texture when served on top of the hot soup.
The step that matters
Slowly boil until the liquid reduces to half. A gentle, slow boil concentrates the broth gradually and extracts flavor cleanly. Vigorous boiling can cloud the liquid and make it greasy.
