What each ingredient does
- Barberries
- Provide the tart fruit flavor and pectin-rich body that forms the jam's structure.
- Brown sugar
- Sweetens the jam and, as it dissolves and concentrates, helps it set to a spreadable consistency.
- Cold water
- Helps the sugar dissolve evenly so the fruit does not scorch before it softens.
The step that matters
Cook the jam slowly for one hour. Sugar can scorch on the bottom of the kettle if heat is too high or stirring is neglected. Slow simmering with occasional stirring lets water evaporate and the jam thicken without burning.
