Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cow-heel
- Provides collagen and gelatin from bones and connective tissue, giving the broth body and richness.
- Onion
- Adds savory sweetness and aromatic depth to the broth as it simmers.
- Carrot
- Contributes gentle sweetness and color to the broth during long simmering.
- Celery
- Adds aromatic, savory flavor to the broth as it simmers.
- Sago or crushed tapioca
- Thickens the broth as its starch gelatinizes when boiled.
The step that matters
Skim off any foam after the first boil. Foam carries impurities and proteins that can cloud the broth and taint its flavor. Removing it early keeps the soup clear and clean-tasting.
