1 litre of vodka
600g castor sugar
300ml water

Equally pour the vodka into the two sterilized bottles, and again equally share the sugar syrup and the blackberries between the two.
Place cinnamon stick in each bottle, then replace the lid and store away in a cupboard for at least two weeks to a month, shaking occasionally.
Strain the liquer through a fine muslin, before bottling up and placing back into the cupboard for a further month.
