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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Pineapples
- Provide the fruit base, along with pectin and acid that help the mixture thicken as it cooks.
- Granulated sugar
- Sweetens the preserve and, as it dissolves and concentrates, helps it set into a thick spread.
The step that matters
Cook until clear and thick. Sugar and fruit must be cooked long enough for water to evaporate and the mixture to reach a set point. Stopping early leaves it runny, while overcooking can scorch the sugar and darken the flavor.
