What each ingredient does

Raspberries
Provide the fruit, pectin and acid that give the jam its flavour and body.
Sugar
Sweetens the jam and helps it thicken and set as it cooks.

The step that matters

Stirring until thick and jelly-like. Sugar and fruit pectin set into a gel only when the mixture reaches a high enough concentration. Stopping too early leaves a runny jam, while cooking too long can make it stiff and candy-like.
