Why it works: Sugar and pineapple 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 Pine-apples
Ingredients
Directions
Prepare
Pare and slice the pineapples nicely.
Cover the slices with sugar and let them stand for a day or night.
Make the syrup
In the morning, remove the pineapples and boil the syrup.
When the syrup simmers, add the pineapples back and boil for 15 minutes.
Remove the pineapples and let the syrup boil longer.
Once both are cool, pour the syrup over the pineapples.

What each ingredient does
- Pineapples
- Provide the fruit that is preserved and sweetened in the syrup.
- Loaf sugar
- Draws moisture out of the fruit and forms the sweet syrup that preserves it.
The step that matters
Letting the syrup boil longer after removing the pineapples. Boiling the syrup further thickens it as water evaporates, concentrating the sugar. A syrup that is too thin will not preserve the fruit well, so the sugar concentration needs to rise before the syrup is poured back over the pineapples.
