What each ingredient does
- Raspberries
- Provide the main fruit flavour and most of the jam's body.
- Sugar
- Preserves the fruit and helps it set into a gel as the mixture thickens.
- Red currant juice
- Adds tartness and natural pectin to help the jam set.
The step that matters
Boil for 20 minutes, skimming off any foam.. The mixture must reach a concentration of sugar and acid high enough to gel as it cools. Skimming removes foam so the jam stays clear and does not spoil its appearance.
