What each ingredient does

Strawberries
Provide the fruit flavor and the bulk of the jam's body.
Sugar
Sweetens the jam, helps it thicken and set, and helps preserve it.

The step that matters

Stirring to prevent scorching. Sugar-rich fruit sticks and burns on the bottom of the pot as the juice thickens. Scorched sugar turns bitter and dark, so frequent stirring keeps the jam tasting fresh.
