Scoop out the pulp, removing seeds and white inner skin.
Weigh the pulp and rind together.

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 and pectin-rich pulp that give marmalade its characteristic flavour and set.
- Loaf sugar
- Sweetens the marmalade and, when boiled, helps it set and preserves it.
The step that matters
Boiling after adding the sugar. Sugar must dissolve fully and the mixture must reach a rolling boil so pectin and acid can set the marmalade; boiling too briefly leaves it runny, while overboiling can darken and toughen it.
