  Meanwhile, to make the raspberry sorbet, combine sugar and 1 cup (250ml) water in a saucepan over low heat. Cook, stirring, for 3 mins or until sugar dissolves. Increase heat to high. Bring to the boil. Cook, without stirring, for 5 mins or until syrup thickens slightly. Remove from heat. Add the raspberries and stir to combine. Set aside to cool.

  Place the raspberry mixture in a food processor and process until smooth. Strain through a fine sieve into a metal container, using a spatula to press as much pulp through as possible. Cover with foil and place in the freezer. Freeze for 6 hours or until frozen. Working quickly, use a metal spoon to transfer mixture to a food processor and process until smooth. Spoon half the sorbet over yoghurt mixture and smooth the surface. Cover with foil and place in the freezer to set. Refreeze remaining sorbet.
