Why it works: Orange and sugar are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 19,212 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Shared aroma: beta-damascenone (apple, rose).
Orange and sugar barely smell alike, yet cooks put them together in 19,212 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Orange juice
- Provides the liquid base and the citrus flavour of the syrup.
- Sugar
- Sweetens the syrup and, as it dissolves and thickens on boiling, gives it body.
The step that matters
Boil slowly for 10 to 15 minutes. Boiling concentrates the juice and dissolves the sugar fully. Too short a boil leaves a thin syrup that may spoil sooner, while overboiling can make it too thick once it cools.
