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 flavor team
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
- Pineapple
- Supplies the fruit, flavour and acidity that give the marmalade its character and body.
- Loaf sugar
- Sweetens the marmalade and, as it cooks down, helps it thicken into a spreadable preserve.
The step that matters
Boiling the syrup until clear. Scum is foam of impurities that rises as the syrup boils. Skimming it away until the syrup runs clear keeps the finished marmalade clean-tasting and free of cloudiness.
