What each ingredient does
- Bones
- Release collagen, gelatin and minerals into the water, giving the broth body and depth.
- Onion
- Adds savory sweetness and aroma to the broth as it simmers.
- Carrot
- Contributes subtle sweetness and aromatic flavor to the broth.
The step that matters
Skim off the foam. Foam carries coagulated proteins and impurities that can cloud the broth and make it taste bitter or dull. Skimming early keeps the broth clear and clean.
