To make the citrus juice: Add peeled pieces of fruit and water to a blender and blend on high for 1 minute. Taste and add ½-1tbsp honey if too tart, blend again and then strain into a container for use in cocktails.
To make one cocktail: In a cocktail glass stir together vodka and citrus juice. Then, add crushed ice or ice cubes followed by a top up with the ginger soda or ginger beer. Garnish with citrus and mint. Cheers!
