    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

Oranges
Provide the juice that forms the base of the syrup and its bright flavour.
Sugar
Sweetens the juice and, when dissolved and boiled, thickens it into a syrup.

The step that matters

Boil slowly and skim the foam. Sugar dissolves into the juice and the mixture thickens as water evaporates. Boiling too hard can scorch the sugar, and foam left on the surface can cloud the syrup or spoil it in storage.
