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 ↓
Pine Apple Preserves
Ingredients
Directions
Prepare the fruit
Pare and slice the pineapples thinly.
Weigh the fruit and use 1 pound of sugar for each pound of fruit.
In a deep bowl, layer the fruit and sugar alternately, finishing with a layer of sugar on top.
Let it stand overnight.
Make the syrup
In the morning, remove the fruit and pour the syrup into a preserving kettle.
Boil and skim the syrup until clear.
While hot, pour the syrup over the fruit.
Let it cool uncovered.
Jar and seal
Once cooled, pack the fruit into glass jars or tumblers and seal with paper.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: 2-nonenal (fatty, green).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe pineapples
- Provide the fruit that forms the body and flavor of the preserve.
- Double-refined loaf sugar
- Draws moisture out of the fruit and forms a syrup, while preserving and sweetening the fruit.
The step that matters
Boil and skim the syrup until clear. Sugar syrup must reach a full boil so that it is hot enough to help preserve the fruit, and skimming removes foam and impurities that would otherwise cloud the syrup and spoil the preserve.
