What each ingredient does
- Red currants
- Provide the tart acidity and natural pectin that help the jam set.
- Sugar
- Sweetens the fruit and, as it dissolves and concentrates, helps the jam thicken and keep.
- Raspberries
- Add sweet floral aroma and fruity flavour to balance the tart currants.
The step that matters
Skim off any foam and boil gently for 45 minutes. Foam hides scum and air that can cloud the jam, and a gentle boil concentrates the fruit and sugar without scorching. A rolling boil that is too hard can burn the sugar and break down the fruit's pectin, weakening the set.
