Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main meat and rich flavour that gives the broth its body.
- Pearl barley
- Its starch thickens the broth slightly and gives the soup a hearty texture.
- Prunes
- Add sweetness and a deep, fruity note that balances the savoury broth.
- Cabbage
- Soaks up broth flavour and adds soft, mild body to the soup.
The step that matters
Skimming the scum as the broth boils. Foam rising from the meat contains coagulated proteins and impurities. Removing it as it forms keeps the broth clear and clean-tasting instead of cloudy and greasy.
Swap the fennel
How well each one fits the dish's main ingredients (mutton, pepper, cabbage, carrot, onion, barley):
