What each ingredient does
- Rhubarb
- Provides the main fruit body and tartness that the jam is built around.
- Sugar
- Sweetens the jam and helps it thicken as it cooks down and sets.
The step that matters
Cooking until the mixture thickens. Sugar and rhubarb must cook long enough for the water to evaporate and the pectin in the fruit to set. Stopping too early leaves a runny jam, while cooking too long can scorch the sugar and make it stiff.
