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 ↓

What each ingredient does
- Pineapple
- Provides the fruit base, flavor, and pectin-bearing pulp that thickens the marmalade.
- Granulated sugar
- Sweetens the marmalade and, as it cooks down, helps it thicken and set.
The step that matters
Cook until the mixture is clear and thick. Sugar and fruit must be cooked long enough for water to evaporate and the sugar to concentrate, so the marmalade sets when cooled. Stopping too early leaves it runny; overcooking can scorch the sugar and make it stiff.
