What each ingredient does

Greengages
Provide the fruit flavour, natural pectin and body that give the jam its structure.
Sugar
Sweetens the jam and helps it set as it thickens during boiling.

The step that matters

Boiling quickly while stirring and skimming. Sugar and fruit must reach a high enough concentration to gel, and sugar can scorch on the base of the pot if not stirred. Skimming foam removes impurities so the jam stays clear and clean-tasting.
