What each ingredient does
- Blackberries
- Provide the fruit, flavor, and natural pectin that help the jam thicken and set.
- Sugar
- Sweetens the jam, binds water, and helps it thicken and keep well.
The step that matters
Skim and stir while boiling. Sugar-rich fruit mixtures can scorch on the bottom of the kettle if not stirred often. Skimming the foam keeps the jam clear and fresh-tasting.
