What each ingredient does
- Blackberries
- Provide the main fruit body, flavor, and bulk of the preserve.
- Sugar
- Sweetens the preserve and, at this quantity, helps it thicken and keep.
- Vinegar
- Adds acidity that balances the sweetness and brightens the fruit flavor.
The step that matters
Scalding the mixture the second time. Heating the fruit and sugar again after standing draws out more juice and dissolves remaining sugar. Overheating can scorch the sugar and darken the flavor, so keep it at a scald rather than a hard boil.
