What each ingredient does
- Pie plant (rhubarb)
- Provides the tart flavor and the juice that becomes the jelly.
- Sugar
- Adds sweetness and, as it concentrates in the cooking juice, helps the jelly thicken and set.
The step that matters
Cooking to the desired thickness. Sugar and the natural pectin in the juice set only once enough water has evaporated and the mixture is concentrated. Stopping too early leaves a runny jelly, while cooking too long makes it stiff and can cause crystallisation or scorching.
