Transfer mixture to an ice cream maker (mine only fit half of the mixture at one time).
Process rosé mixture until it turns into slush. Mine took about 10 minutes.
Serve the Frozen Strawberry Rosé Slushies immediately (store anything that's unused in the freezer). Enjoy!
If you don't have an ice cream maker, skip chilling step. Instead, mix together puree and rosé in a 13 x 9-inch pan, cover, and freeze until mostly solid. Transfer mixture to a blender and blend until smooth.
