What each ingredient does

Blackberries
Provide the fruit juice that forms the body and flavour of the syrup.
Loaf sugar
Sweetens the syrup and, at high concentration, helps preserve it.
Brandy
Adds alcohol that aids preservation and contributes aroma to the syrup.

The step that matters

Skimming during the gentle boil. Foam and fruit solids rise to the surface as the juice boils. Skimming them off keeps the syrup clear and reduces spoilage risk before bottling.
