Why it works: Sugar and plum 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 ↓
Damson Jam
Ingredients
Directions
Prepare the fruit
Wash the plums, remove the stones, and weigh them.
Cook the jam
Layer the plums and sugar in a saucepan, allowing them to stand until some juice is extracted or add a small amount of water to moisten the bottom.
Heat gradually to boiling, then boil gently, stirring frequently until the fruit loses its shape and the juice thickens to a molasses consistency.
Pot and set
Pour the mixture into hot jelly glasses and cover once completely cool.

What each ingredient does
- Plums
- Provide the fruit, pectin and acid that give the jam its body and flavour.
- Sugar
- Draws out juice and thickens the jam while preserving it and adding sweetness.
The step that matters
Boil gently while stirring frequently. Sugar and fruit can scorch on the bottom of the pan if left unstirred, and the jam must reach a thick, molasses-like consistency to set properly once cooled.
