What each ingredient does
- Raspberries
- Provide the fruit, pectin and flavor that form the body of the jam.
- Sugar
- Sweetens the jam and helps it set by binding water and thickening the fruit.
The step that matters
Boil gently after adding sugar. Sugar must dissolve fully before a gentle boil; too vigorous a boil can scorch the sugar and fruit, while too short a boil leaves the jam runny because pectin and sugar need time to reach setting concentration.
