Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. 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 liquid into a firm, sliceable gel that holds the vegetables in place.
- Celery
- Adds crunch and fresh texture that stays firm within the gel.
- Cabbage
- Adds crisp texture and bulk to the set salad.
- Green peppers
- Adds crisp texture and a fresh, slightly bitter vegetable flavour.
- Lemon juice
- Adds acidity that brightens the sweetness and balances the gelatine.
- Sugar
- Adds sweetness that balances the vinegar and lemon acidity.
The step that matters
Stirring the mixture over the vegetables until it begins to congeal. If the gelatine has not started to thicken, the vegetables will sink to the bottom instead of staying suspended. If it has set too far, it will not pour evenly into the cups or mold. Gelatine sets as it cools, so timing matters.
Swap the cabbage
How well each one fits the dish's main ingredients (celery, pepper, sugar, lemon, vinegar):
- Mustardfits better
- Capsicumfits better
- Carrotfits better
- Cabbagethe original
Fit is the average pairing score against celery, pepper, sugar, lemon, vinegar. Candidates are from the same food group and used in at least 100 recipes.
