Put all the ingredients into a blender, and blitz until smooth.
Put the mixture into a container with a lid. Place in the freezer until fully frozen or overnight, which we found gave the best result.
Remove the frozen mixture from the freezer and cut into cubes. Put the cubes into a blender and blitz again to break down the ice crystals until you get a smooth consistency. Enjoy straight away or place in the freezer again to allow the sorbet to firm up a little.
Garnish with fresh raspberries, fresh mint and a raspberry coulis.
