What each ingredient does
- Mutton
- Supplies the meaty flavour, and its collagen gives the broth body as it simmers.
- Onion
- Adds aromatic, mildly sweet flavour to the broth as it simmers.
The step that matters
Boil gently. A hard boil toughens the meat's proteins and churns fat into the liquid, making the broth cloudy and greasy. A gentle simmer lets the mutton turn tender while the broth stays clear.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
