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
- Oranges
- Peel and pith supply the bitter aroma and the natural pectin that helps the marmalade set.
- White sugar
- Sweetens the marmalade and, as it concentrates, helps it thicken and set.
The step that matters
Stirring while the mixture cooks. As the mixture thickens and water evaporates, sugar and fruit can stick and scorch on the bottom of the kettle. Frequent stirring spreads the heat evenly and keeps the flavour clean.
