What each ingredient does
- Raspberries
- Provide the fruit flavour, natural pectin and acidity that help the jam set.
- Sugar
- Sweetens the jam and, as it cooks down, helps it thicken and keeps it preserved.
The step that matters
Stirring during the 30-minute boil. Sugar-rich mixtures scorch easily on the bottom of the pot, and burnt sugar gives a bitter taste. Constant stirring spreads the heat evenly and keeps the jam from sticking while the water evaporates and it thickens.
