Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef from shank
- Connective tissue breaks down during long simmering, giving the broth body and richness.
- Tomatoes
- Add acidity and fresh, bright flavor to the broth.
- Onion
- Provides savory aromatic depth as it softens into the broth.
- Carrots
- Add gentle sweetness that balances the savory beef flavor.
- Potatoes
- Release starch as they cook, lightly thickening the broth.
The step that matters
Skim off the foam after boiling. Foam rises from proteins and impurities released by the beef. Removing it early keeps the broth clearer and cleaner-tasting, rather than cloudy or scummy.
Swap the cabbage
How well each one fits the dish's main ingredients (beef, tomato, parsley, celery, turnip, potato, onion):
- Carrotfits better

- Leekfits better
- Cabbagethe original
Fit is the average pairing score against beef, tomato, parsley, celery, turnip, potato, onion. Candidates are from the same food group and used in at least 100 recipes.
