In a bowl, whisk together all the ingredients. Chill well, and then freeze in an ice-cream maker according to the manufacturer’s directions. Transfer to a lidded storage container, cover and freeze for at least 1 hour to firm.
At serving time, remove the sorbet from the freezer. If it is hard or icy, let stand at room temperature until soft enough to scoop. Put a generous scoop in each of 6 serving dishes.
