What each ingredient does
- Strawberries
- Provide the fruit body, flavor, and natural pectin that help the preserves set.
- Sugar
- Sweetens the fruit, draws out moisture, and helps the preserves thicken and keep.
The step that matters
Boil rapidly for 20 minutes. Sugar must be fully dissolved before boiling, and the rapid boil concentrates the syrup and activates pectin so the preserves set. Under-boiling leaves them runny, while over-boiling can scorch the sugar and darken the flavor.
