What each ingredient does
- Grapes
- Provide the flavor, color, and pulp that make up the body of the preserve.
- Sugar
- Sweetens the mixture and helps it thicken as the liquid reduces by boiling.
The step that matters
Boil until thick after adding sugar. Sugar dissolves into the hot liquid and raises its boiling point while concentrating it. Boiling long enough drives off water so the mixture thickens, which is what keeps it firm and stable once canned. Stopping too early leaves it thin.
