What each ingredient does

Fruit
Provides the pectin, acid and pulp that set the marmalade into a thick, spreadable mass.
Sugar
Sweetens the marmalade and helps it thicken and set as it cooks down.

The step that matters

Cook slowly until a thick, jelly-like mass forms. Cooking gently and stirring often keeps the sugar from scorching and lets the fruit's pectin and acid set the mixture evenly. Too much heat can burn the sugar or leave the fruit tough.
