Peel the ginger skin and add the finely chopped pieces to a tall glass. Muddle it lightly to release more spice and flavour.
Scoop out the contents of half of a passion fruit into the glass and mix with the ginger.
Add ice cubes to the glass and fill with the Kopparberg Elderflower & Lime cider.
Garnish with the remaining one half of the passion fruit and lime wheels.
