What each ingredient does
- Strawberries
- Provide the fruit flavor, color, and body of the jam.
- Sugar
- Sweetens the jam, helps it set, and helps preserve it.
The step that matters
Skimming after each boil-up. Foam rises to the surface as the fruit boils. Skimming it off each time keeps the jam clear and free of off-flavors, while the boiling drives off water and concentrates the sugar so the jam can set.
