What each ingredient does

Berries
Provide the fruit flavour, natural pectin, and bulk of the jam.
Brown sugar
Sweetens the jam and helps it thicken and set as it cooks down.

The step that matters

Stir continuously while boiling. Sugar-rich fruit mixtures scorch easily on the bottom of a pot. Constant stirring spreads the heat evenly and keeps the sugar from burning, which would give a bitter taste.
