Why it works: Plum and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 2,313 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
Canned Plums
Ingredients
Directions
Prepare
Prick the plums to prevent breaking.
Layer the plums and sugar alternately in a preserving kettle.
Let them sit on the back of the stove for 1-2 hours.
Cook and jar
Place the kettle over moderate heat and bring to a boil.
Skim off any foam and pour the mixture into jars.
Run a silver spoon handle around the inside of the jar to break air bubbles.
Cover and screw down the tops.

What each ingredient does
- Plums
- Provide the fruit, along with their juice, which dissolves the sugar and forms the syrup.
- Sugar
- Draws out juice from the plums and acts as a preservative, adding sweetness that balances the fruit's tartness.
The step that matters
Let the plums sit with sugar before heating. Resting the fruit in sugar draws out juice so the sugar dissolves into a syrup before boiling. Heating too early can leave undissolved sugar and uneven texture, and skimming foam keeps the jars clear.
