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 ↓
To Preserve Pineapples
Ingredients
Directions
Prepare the fruit
Peel the pineapples and remove the eyes.
Hold the fruit by the tops and scrape down with a fork until only the core remains.
Weigh the fruit and combine it with an equal amount of sugar in a porcelain-lined or granite kettle.
Cook and store
Heat over the fire, stirring with a silver or wooden spoon.
Boil until the fruit becomes transparent, then remove from heat.
Transfer to glass jars or jelly glasses for storage.

What each ingredient does
- Pineapples
- Provide the fruit that softens and turns transparent as it cooks in syrup.
- Sugar
- Sweetens the fruit and draws out moisture to form a preserving syrup.
The step that matters
Boil until the fruit becomes transparent. Sugar must dissolve fully and the fruit must cook through, so it absorbs syrup and stays preserved. Stopping too early leaves it opaque and less stable; overcooking can make it dark and sticky.
