Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle
- Contributes gelatin and body, giving the broth its jelly-like texture when cooled.
- Lean beef
- Adds meaty flavour to the broth as it simmers.
- Poultry or meat trimmings and bones
- Release collagen and savoury flavour into the liquid during long simmering.
The step that matters
Skimming during the simmer. Impurities and fat rise to the surface as the meat cooks. Skimming them regularly keeps the broth clear and clean-tasting rather than cloudy or greasy.
Swap the parsley
How well each one fits the dish's main ingredients (veal, beef, meat, onion):
- Garlicfits better
- Celeryfits better
- Thymefits better
- Parsleythe original
Fit is the average pairing score against veal, beef, meat, onion. Candidates are from the same food group and used in at least 100 recipes.
