What each ingredient does
- Rhubarb
- Provides the fruit body and tart flavour, and its pieces hold their shape in the jam.
- Sugar
- Draws out the rhubarb's juice to form syrup, adds sweetness, and helps the jam set and keep.
The step that matters
Boil the syrup until it thickens. Sugar syrup must reach a high enough concentration before the fruit goes in. Boiling it down first lets the jam thicken and set properly instead of staying runny.
