Strain your strawberry simple syrup and measure out 6-8 tablespoons (to suit your sweetness level).
In your blender add the frozen rosé, your strawberry simple syrup and vodka and give it a whirl.
Pour into pretty glasses, garnish with a small strawberry and serve!
If you aren't quite ready to serve you can put the mixture back into the freezer and give it a quick blend right before serving.
