What each ingredient does

Seville oranges
Provide the bitter peel and pectin-rich pulp that give marmalade its flavour and set.
Sugar
Sweetens the marmalade and helps it set by binding water and concentrating the mixture.

The step that matters

Boiling the mixture gently while stirring. Boiling too hard or without stirring can scorch the sugar and dull the flavour, while too little heat may prevent the pectin from setting properly.
