    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

Seville oranges
Supply the bitter peel and pectin that give marmalade its flavour and set.
Sugar
Sweetens the bitter fruit and helps the mixture gel when boiled to setting point.

The step that matters

Boiling to a jelly-like set. Boiling must reach the gel point, where the sugar and pectin set on cooling. Stopping early leaves a runny marmalade; boiling too long can darken the flavour and make it overly stiff.
