Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

What each ingredient does
- Plums
- Provide the fruit, which softens and turns clear as it is heated in the syrup.
- Sugar
- Sweetens the fruit and, boiled into a thick syrup, preserves it.
- Water
- Dissolves the sugar to make the syrup that surrounds and preserves the plums.
The step that matters
Skim the syrup clear. Scum rising on boiling syrup can cloud the preserve and spoil its appearance, so it must be removed before the syrup is poured back over the fruit.
