What each ingredient does

Barberries
Provide the fruit base and tart flavor that define the jam.
Powdered sugar
Adds sweetness and helps set the jam by binding with fruit pectin as it cooks.

The step that matters

Stirring during the boil. Sugar-heavy fruit mixtures can scorch on the bottom of the pot before the rest reaches a boil. Stirring occasionally distributes heat evenly and keeps the jam from burning while it thickens.
