Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Scotch barley
- Swells during long simmering, thickening the broth and giving it a chewy body.
- Shin or leg of beef
- Releases gelatin and flavor into the broth during the long, gentle simmer.
- Onions
- Add sweetness and savory depth as they cook down into the broth.
- Celery
- Adds aromatic, vegetal flavor that rounds out the broth.
- Turnip
- Contributes mild sweetness and body as it softens in the broth.
The step that matters
Skim the surface and fat. Foam and fat rise as the broth heats and cooks. Skimming them keeps the broth clear and prevents a greasy, cloudy result.
Swap the onion
How well each one fits the dish's main ingredients (barley, beef, celery, turnip):
