Why it works: Peach and lemon work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 947 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
- Peaches
- Provide the main fruit flavour and most of the body of the marmalade.
- Sugar
- Sweetens the fruit and helps thicken the mixture as it cooks down.
- Lemon juice
- Adds acidity that brightens the flavour and supports gel setting.
- Peach stone kernels
- Add a subtle bitter almond aroma to the marmalade.
The step that matters
Stirring while the peaches heat slowly. Peach flesh and sugar scorch easily on the base of a pot when heated without frequent stirring. Scorched sugar gives a burnt, bitter taste that spoils the whole batch.
Swap the lemon

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