What each ingredient does
- Blackberries
- Provide the fruit flavor, natural pectin and most of the jam's body once cooked down.
- Sugar
- Sweetens the jam and helps it thicken and keep by binding water and softening fruit acidity.
The step that matters
Boiling the mixture. Sugar and fruit must cook long enough for the mixture to reach the gel point. Stopping too early leaves runny jam, while overcooking can scorch the sugar and dull the flavor. Stirring prevents sticking and burning on the bottom of the pot.
