What each ingredient does
- Calf's head
- Provides the main body, gelatin and meat that give the soup its rich texture.
- Carrots
- Add natural sweetness and aromatic flavour to the simmering broth.
- Onion
- Adds savoury depth and aroma to the broth as it cooks.
The step that matters
Cook until the head is quite tender. Calf's head is rich in collagen, which only breaks down into gelatin with long, gentle simmering. Stopping early leaves the meat tough and the broth thin, so cook until the meat is fully tender.
