Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley
- Thickens the broth as its starch softens during gentle simmering, and gives the soup body and chew.
- Mutton
- Releases collagen and flavor into the water during long cooking, enriching the broth.
- Ham
- Adds savory, smoky depth to the broth as it simmers.
- Turnip
- Contributes mild sweetness and aroma as it cooks into the broth.
- Onion
- Adds aromatic sweetness and savory background to the broth.
The step that matters
Adding the barley. Barley should be added only after the broth is strained and seasoned, then simmered gently. Boiling hard can break the grains apart and cloud the broth, and the starch will keep thickening it the longer it sits in the hot liquid.
Swap the onion
How well each one fits the dish's main ingredients (mutton, ham, turnip, barley, pepper, parsley):
- Leekfits better

Fit is the average pairing score against mutton, ham, turnip, barley, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
