Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main meaty flavour, which deepens during long, slow simmering.
- Bone
- Releases gelatin during simmering, giving the broth body and a richer mouthfeel.
- Peppercorns
- Add a sharp, aromatic warmth to the broth.
- Cloves
- Add a strong, warm aroma that flavours the broth.
- Mixed herbs
- Add aromatic, savoury notes that blend into the broth.
The step that matters
Add the water and heat slowly. Starting with cold water and heating gently draws flavour and gelatin out of the meat and bone while keeping the broth clear. Boiling hard churns fat into the liquid and clouds it, so the finished bouillon tastes muddier.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, clove):
- Carrotfits better

Fit is the average pairing score against beef, clove. Candidates are from the same food group and used in at least 100 recipes.
