What each ingredient does

Fruit
Provides the main flavor, pectin, and bulk of the jam.
Sugar
Adds sweetness and helps the jam set and keep its texture.

The step that matters

Boiling the mixture. Boiling long enough drives off water so the mixture thickens. Stopping too early leaves a runny jam, while overcooking can make it stiff and cause the sugar to scorch on the bottom of the pot. Stirring helps prevent sticking.
