Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 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
- Cold meat
- Forms the body of the loaf and gives it its main flavour.
- Gelatine
- Sets the strained broth so it holds the meat together when chilled.
- Onions
- Add aroma and savoury flavour to the broth as it boils.
The step that matters
Dissolving the gelatine into the broth. Gelatine must be fully dissolved in warm broth before it is added, otherwise it can form lumps and fail to set evenly. Once chilled, gelatine forms a gel network that holds the loaf firm enough to slice.
Swap the onion
How well each one fits the dish's main ingredients (meat, pepper):
- Capsicumfits better
- Mustardfits better

- Onionthe original
Fit is the average pairing score against meat, pepper. Candidates are from the same food group and used in at least 100 recipes.
