What each ingredient does

Raspberries
Provide the main fruit flavor, color, and bulk of the jam.
Currant juice
Adds acidity and natural pectin that help the jam thicken and set.
Sugar
Sweetens the jam, helps it set, and preserves it by binding water.

The step that matters

Boil for the additional 10 minutes after adding sugar. This final boil drives off water and lets the pectin and sugar form a gel. Stirring prevents scorching on the bottom, and skimming removes foam so the jam looks clear.
