    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 orange rinds
Provide bitter peel flavour and chewy texture, and pectin-rich material that helps the preserve set.
Seville orange pulp and juice
Supply acidity and pectin, which help the marmalade thicken and set.
Sugar
Sweetens the preserve and, when boiled, thickens it into a syrup and helps it set.

The step that matters

Boil until the mixture thickens into a syrup. Sugar and pectin must be concentrated by boiling to reach the setting point. Too little boiling leaves the marmalade runny, while overcooking can make it stiff and darken its flavour.
