What each ingredient does
- Rhubarb
- Provides the tart flavor and the fruit pieces that make up the jam.
- Sugar
- Sweetens the jam and, as it cooks, helps it thicken into a spreadable set.
The step that matters
Boiling the syrup until it thickens. Sugar and pectin only set when the syrup reaches the right concentration. Boiling too briefly leaves the jam runny, while boiling too long can make it stiff or scorch the sugar.
