Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb's head
- Gives the broth its meaty flavour and body as it simmers for hours.
- Rice or pearl barley
- Adds body and a soft, starchy thickness to the broth.
- Carrot
- Adds sweetness and aroma to the broth.
- Onion
- Adds savoury depth and aroma as it softens in the broth.
- Turnip
- Adds mild sweetness and earthy flavour to the broth.
The step that matters
Remove any scum. Scum is coagulated protein and impurities that rise as the water heats. Skimming it early keeps the broth clear and stops off flavours from spreading through the liquid during the long simmer.
Swap the onion
