What each ingredient does

Raspberries
Provide the main fruit flavor, color and bulk of the jam.
Currant juice
Adds natural pectin and acidity that help the jam set.
Sugar
Adds sweetness and, with boiling, helps the jam thicken and set.

The step that matters

Boiling after the sugar is added. Once the sugar dissolves, the jam must boil long enough to reach a concentration where pectin and acid form a gel. Too little boiling leaves it runny, while too much can make it stiff, dull or scorched on the bottom of the pot.
