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
Peel and slice the pineapples.
For each pound of fruit, use a pound of sugar.
Layer the sugar and fruit in a deep bowl, with sugar on top and bottom.
Let the pineapple sit overnight.
Make the syrup
In the morning, strain the syrup into a preserving kettle.
Place the kettle over the fire and boil gently, skimming until clear.
Continue boiling slowly until a cooled drop thickens to a medium consistency.
Pour the syrup back over the pineapple and let it cool.
Once cold, store the preserves as directed in the pineapple jelly recipe.

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.

What each ingredient does
- Ripe pineapples
- Provides the fruit that gives the preserves their flavor and body.
- Sugar
- Draws out juice and, once boiled, thickens the syrup and preserves the fruit.
The step that matters
Boiling the syrup to a medium consistency. Boiling concentrates the sugar and sets the syrup. Stopping too early leaves it runny, while boiling too long can make it stiff or cause sugar to crystallize. Testing a cooled drop shows when it has reached the right point.
