1. Pour the whole bottle of rosé into a shallow baking dish with a lid. Secure lid and place in freezer for at least 8 hours or overnight. 

2. In a blender add the frozen rosé, Grand Marnier, sugar, strawberries and ice. 

3. Blend until there is a slushy consistency (about 20 seconds). 

4. Serve in a coup with a fresh strawberry as a garnish. 

*Note: I like my frosé on the less sweet side so I can actually taste the other ingredients but if you like a sweeter drink, add ¼ cup sugar.
