    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
Provide the bitter peel, pulp and juice that give marmalade its characteristic flavour and set.
Seeds (in the method)
Soaked and strained to release pectin, which helps the marmalade set.
Sugar
Sweetens the marmalade and, once boiled, helps it thicken and set.

The step that matters

Boiling the mixture with sugar added in stages. Adding sugar in portions and boiling until thick lets the pectin and acid set the marmalade. Boiling too briefly leaves it runny, while overboiling can darken and toughen it.
