Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley
- Thickens the soup as its starch releases during long simmering.
- Neck of mutton
- Adds rich meaty flavour and body to the broth during the long cook.
- Lean ham
- Adds savoury, salty depth to the broth.
- Onions
- Build aromatic sweetness and flavour as they soften in the broth.
- Carrots
- Add gentle sweetness and colour, and soften into the soup.
- Turnips
- Add mild earthy flavour and soften into the soup during cooking.
The step that matters
Cook gently for 2 hours. A gentle simmer lets barley and meat release flavour and starch slowly. A hard boil can break up vegetables and make the broth cloudy.
