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 Preserves
Ingredients
Directions
Prepare the fruit
Remove the top and bottom of the pineapples and peel off the rough skin.
Weigh the pineapples and cut them into slices, chips, or quarters.
Cook the fruit and syrup
For each pound of fruit, add ½ cup of water to a preserving kettle and bring to a gentle boil until the fruit is tender and clear.
Remove the fruit using a fork or skimmer and place it in a dish.
Add 1 pound of sugar for each pound of fruit to the water and stir until dissolved.
Return the pineapple to the kettle, cover, and boil gently until transparent throughout.
Remove the fruit and let it cool, then place it in glass jars.
Simmer the syrup until thick and rich, then pour it over the fruit.
Seal
Seal the jars the next day.

What each ingredient does
- Pineapples
- Provide the fruit that becomes tender and turns transparent as it cooks in the syrup.
- White sugar
- Sweetens the preserve and, when boiled into syrup, thickens it and helps the fruit turn clear.
The step that matters
Boil the fruit gently until transparent throughout. Boiling hard can break the pineapple apart and cloud the syrup. Gentle heat lets sugar slowly penetrate the fruit so it becomes clear and holds its shape.
