Shared aroma: beta-damascenone (apple, rose).
Sugar and orange 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 and pectin that give marmalade its characteristic flavour and set.
- Sugar
- Sweetens the marmalade and helps it set and keep by binding water.
The step that matters
Boil slowly until the chips are tender and clear. Peel must cook long enough to soften fully; undercooked chips stay tough and cloudy. Slow boiling also lets water evaporate gradually so the sugar and pectin can set the marmalade without scorching or over-thickening.
