Prepare

What each ingredient does
- Rhubarb
- Provides the tart flavour and the bulk of the jam, softening as it cooks.
- Fine powdered sugar
- Sweetens the jam and helps it thicken and set as it boils down.
The step that matters
Boiling the mixture rapidly after the rhubarb is tender. Sugar needs a hard, sustained boil to concentrate the liquid and reach the level where the jam sets. Stopping too early leaves it runny, while stirring well prevents the sugar from scorching on the bottom of the pan.
