Place strawberries, sorbet, sugar and 240ml (1 cup) of wine in a blender or food processor. Blend on high speed until mixture is smooth. Transfer mixture to a freezer-proof container (I use a glass container) and freeze until solid (at least 3-4 hours or overnight).

Remove mixture from the freezer and transfer it to a blender (or food processor). Add remaining wine and ice cubes, blend on high speed until somewhat smooth (it’ll have an icy, thick texture, but you don’t want any big ice chunks).

Serve right away or put back into the freezer until serving time.
