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
Twist off the top and bottom of the pineapples and remove the rough skin.
Weigh the pineapples and cut them into slices, chips, or quarters.
Cook the fruit
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.
In the remaining water, add 1 pound of sugar for each pound of fruit and stir until dissolved.
Add the pineapple back to the kettle, cover, and boil gently until transparent.
Remove the fruit.
Make the syrup and jar
Let it cool.
Transfer it to glass jars.
Simmer the syrup until thick and rich.
Pour the syrup over the fruit.
Seal the jars the next day.

What each ingredient does
- Pineapples
- The main fruit, which provides the flavour and the bulk of the preserve.
- White sugar
- Sweetens the preserve and, as it thickens, helps set the syrup and preserve the fruit.
The step that matters
Simmering the fruit until transparent. Boiling gently keeps the pineapple pieces intact while sugar slowly replaces the water in the fruit, so it turns clear. Boiling hard can break the pieces apart and make the syrup cloudy.
