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 ↓
Greengage Preserves
Ingredients
Directions
Prepare the plums
Prick the plums with a fine needle to prevent breaking.
Place the plums in a preserving pan and cover with enough water.
Heat gently until the water simmers.
Remove the plums and drain on a sieve.
Make the syrup
Add 1 lb sugar to the water used for boiling the plums.
Boil quickly, skimming off the scum until the syrup thickens.
Add the plums back to the syrup.
Boil until the sugar bubbles.
Rest and reboil
Pour the mixture into a basin and let it stand overnight.
Drain the syrup from the fruit and boil it quickly.
Pour it over the plums.
Repeat this process for 4 days to cook the fruit without damaging its shape.
Jar and serve
Finally, boil the plums in the syrup for 5 to 6 minutes.
Transfer to jars and pour the syrup over.

What each ingredient does
- Greengage plums
- Supply the fruit itself, which is softened gently so it keeps its shape.
- Sugar
- Sweetens the fruit and thickens the water into a syrup that preserves it.
The step that matters
Reboiling the fruit in syrup. Boiling too hard or too long breaks the skins and collapses the flesh. Gentle, repeated soaking lets sugar slowly replace the water in the fruit, keeping it whole.
