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 ↓
To Preserve Fruit Whole, Without Sugar
Ingredients
Directions
Prepare and pack
Wipe the plums or remove the stems from the cherries and gooseberries.
Pack the fruit tightly in glass jars without bruising.
Cook in water
Screw on the tops tightly and place the jars in a boiler of cold water, covering them.
Bring the water to a boil and watch the jars until the fruit is cooked.
Remove jars when the skins of the plums or cherries split or the gooseberries turn yellow.
Finish and make syrup
Take off the jar tops and fill with fast-boiling water from the kettle.
Quickly screw the tops back on and let cool, tightening again when cold.
For syrup, boil 5 cups of sugar with 6 cups of water for 10 minutes.

What each ingredient does
- Plums
- Fruit that softens and splits as it cooks, giving the preserve its body and juice.
- Green-gages
- Fruit that softens in gentle heat, holding its shape until the skins split.
- Cherries
- Fruit whose skins split as it cooks, releasing juice into the jar.
- Gooseberries
- Fruit that turns yellow as it cooks, signalling it is ready to remove.
- Sugar
- Sweetens the syrup and adds body to the liquid surrounding the fruit.
The step that matters
Remove the jars as soon as the skins split or the gooseberries turn yellow. Fruit left in hot water keeps cooking, so it becomes soft and mushy and loses its shape. Removing it at the first clear sign of doneness keeps the fruit whole and firm.
