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, pectin-rich pulp and sharp flavour that give marmalade its character.
- Loaf sugar
- Sweetens the marmalade and, once dissolved and boiled, helps it thicken and keep its set.
The step that matters
Boiling the pulp and peel until the chips are tender. The peel must soften fully before sugar is added, because sugar hardens the peel and stops it becoming tender. Pectin in the pulp and seeds also needs time to release for a good set.
