Why it works: Pineapple and sugar are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 4,841 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated pineapple
- Provides the fruit base, flavour and bulk of the marmalade.
- Double refined loaf sugar
- Adds sweetness and, as it concentrates, helps the mixture thicken and set.
- Beaten egg whites
- Dries into a paper cover that seals the tumblers.
The step that matters
Cooking until thick. Sugar and fruit must be cooked long enough for water to evaporate and the mixture to thicken and set. Stopping too early leaves it runny and prone to spoiling, while cooking too long can scorch the sugar.

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