Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's head
- Provides the meat and bones that flavour and body the broth as it simmers.
- Onion
- Adds sweetness and savoury aroma to the broth as it cooks.
- Carrots
- Contribute natural sweetness and body to the soup.
- Turnip
- Adds mild sweetness and earthy flavour to the broth.
The step that matters
Simmer for several hours until the meat is tender. Gentle simmering breaks down connective tissue slowly. Boiling hard can toughen the meat and cloud the broth, so keep the liquid at a low, steady simmer until the meat is tender.
