What each ingredient does
- Strawberries
- Provide the fruit flavour and body that the jam is built around.
- Sugar
- Sweetens the jam and helps it thicken and set as it boils.
The step that matters
Boil for 10 minutes. Sugar and fruit must reach a rolling boil long enough for pectin and acid to work and the sugar to concentrate, so the jam sets. Too short a boil leaves it runny and risks spoilage.
