Freeze and/or prick the sloes to allow the juice out. Pile into one (or more) sterilised glass jars.
Tip in the sugar, pour in the vodka and stir a little.
Pop the lid on tightly and store somewhere cool and dark, stirring/shaking occasionally.
After 2-4 weeks, strain off the vodka and seal in sterilised bottles. The alcohol content means that it will keep indefinitely.
