What each ingredient does

Fruit
Provides the main flavor, color, and natural pectin and acid that help the jam thicken and set.
Sugar
Adds sweetness, helps the jam thicken and set, and helps preserve it by binding water.

The step that matters

Stirring during the final boil. Once the sugar is added, the mixture is thick and can scorch on the bottom of the kettle. Stirring continually keeps heat even and lets the jam reach the concentration needed to set.
