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 knuckles
- Bones and connective tissue release gelatin, giving the broth body and a richer mouthfeel.
- Beef shins
- Collagen-rich meat and bone break down during long simmering, adding gelatin and savory depth.
- Juicy beef
- Lean meat cooks into tender pieces that flavor the broth and can be eaten with it.
- Onions
- Release sugars and aromatic compounds during simmering, adding sweetness and savory flavor.
The step that matters
Continue boiling until the meat is tender and falls apart. Collagen in the shins and bones converts slowly to gelatin over long, gentle simmering. Stopping early leaves tough meat and a thin broth. Keep the liquid at a steady simmer rather than a hard rolling boil.
