What each ingredient does
- Raspberries or strawberries
- Provide the fruit bulk, flavour and pectin-containing pulp that forms the jam's body.
- Sugar
- Sweetens the jam and helps it thicken and keep by binding water and setting the pectin.
The step that matters
Cooking until the desired consistency. Sugar and fruit thicken as water evaporates and pectin sets on cooling, so stirring often prevents scorching on the bottom of the pot and the jam may be too runny or too thick if cooked too short or too long.
