What each ingredient does
- Raspberries
- Provide the fruit flavour and most of the bulk of the jam.
- Sugar
- Sweetens the jam, thickens it as it concentrates, and helps it keep.
The step that matters
Add the sugar and cook until thick. Sugar draws water out of the fruit and raises the concentration, which helps the jam thicken and set as it cools. Stopping too early leaves it runny, while cooking too long can darken and scorch the sugar, so cook until thick rather than for a fixed time alone.
