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 ↓
Pineapple Marmalade
Ingredients
Directions
Prepare the fruit
Pare the pineapples and remove the eyes.
Weigh the fruit and measure out an equal amount of sugar.
Grate the flesh of the pineapples using a coarse grater.
Cook the marmalade
Place the grated pineapple in a pot over medium heat and warm gently for 10 minutes until tender.
Gradually add the sugar while stirring, and boil until the mixture thickens and becomes clear.
Pour the marmalade into jars and seal as usual.

What each ingredient does
- Ripe pineapples
- Provide the fruit flesh, natural pectin and acidity that give the marmalade its body and tang.
- Sugar
- Sweetens the fruit and, as it boils, helps thicken the mixture and preserve it.
The step that matters
Gradually add the sugar while stirring, then boil until thick. Adding sugar all at once can cause clumping and uneven dissolving. Stirring keeps it even, and the mixture must reach a full boil so the sugar and fruit pectin set the marmalade properly.
