Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Scotch barley
- Thickens the broth and adds a chewy texture as its starch softens during simmering.
- Leg of beef
- Releases flavour and gelatin into the water, giving the broth body and savouriness.
- Onions
- Contribute sweetness and aroma to the broth as they soften and release their flavour.
- Celery
- Adds aromatic flavour to the broth during the long simmer.
The step that matters
Remove the fat, then add celery, turnip, and carrot pieces.. Skimming fat before adding vegetables keeps the broth clean-tasting and prevents a greasy surface. Adding the vegetables later keeps them from overcooking into mush during the long simmer.
Swap the onion
How well each one fits the dish's main ingredients (barley, beef, celery, turnip, carrot, pepper):
- Leekfits better

- Spinachfits better
- Onionthe original
Fit is the average pairing score against barley, beef, celery, turnip, carrot, pepper. Candidates are from the same food group and used in at least 100 recipes.
