Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the tomato liquid into a firm, sliceable aspic when chilled.
- Cooked or canned tomato
- Provides the main body, flavour and colour of the aspic.
- Egg whites
- Brushed on the moulds, they help the aspic release cleanly when unmoulded.
The step that matters
Soaking and boiling the gelatine. Gelatine must be fully softened and then dissolved completely by heating; if it is not fully dissolved, lumps remain and the aspic will set unevenly.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, egg, lettuce, parsley):
- Capsicumfits better
- Spinachfits better
- Cucumberfits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, egg, lettuce, parsley. Candidates are from the same food group and used in at least 100 recipes.
