What each ingredient does

Strawberries
Provide the fruit, pectin, and flavour that form the body of the jam.
Granulated sugar
Sweetens the jam and helps thicken it as the mixture cooks down.

The step that matters

Cooking the mixture until the desired consistency. Sugar and fruit set into a gel only when enough water evaporates and the mixture reaches a high enough concentration. Stopping too early leaves a runny jam, while cooking too long can make it stiff and taste caramelised.
