What each ingredient does

Strawberries
Provide the fruit, pectin and flavour that form the jam's body and taste.
Sugar
Sweetens the jam and helps it set into a thick, spreadable texture.

The step that matters

Boil the strawberries while stirring constantly. Constant stirring prevents the sugar and fruit from scorching on the bottom of the pan, which would give a burnt taste. Boiling long enough lets the mixture thicken so the jam can set as it cools.
