Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Provides collagen that breaks down into body and richness in the stock.
- Onions
- Browning and frying build sweet, deep savoury flavour in the stock.
- Carrots
- Release natural sweetness and aroma during long simmering.
- Turnips
- Add mild sweetness and aroma to the stock's background flavour.
- Butter
- Carries heat for browning the beef and vegetables and adds richness.
The step that matters
Brown the beef and vegetables well. Browning triggers the Maillard reaction, which creates deep, savoury flavours that a simmered stock cannot develop on its own. Pale meat or vegetables give a flat, washed-out stock.
Swap the onion
How well each one fits the dish's main ingredients (beef, carrot, turnip, parsley, thyme, butter):
- Leekfits better

Fit is the average pairing score against beef, carrot, turnip, parsley, thyme, butter. Candidates are from the same food group and used in at least 100 recipes.
