What each ingredient does

Seville oranges
Provide the bitter peel and pectin that give the marmalade its flavour and set.
Granulated sugar
Sweetens the marmalade and helps it set as it thickens during boiling.

The step that matters

Boil until the marmalade is clear and thick. Sugar must be added in the right proportion and the mixture boiled long enough for pectin and sugar to reach a gel. Undercooked marmalade stays runny, while overcooking can make it dark and stiff.
