I just googled "Cosmopolitan Slushie". Here's the recipe....
Yield: Makes 6 servings
Ingredients
10 ounce (1 1/4 cups) citrus-flavored vodka
1/2 cup Rose's lime juice
2 cups cranberry juice
4 ice cube trays
Preparation
Combine vodka, lime juice, and cranberry juice in a pitcher with 2 cups water and stir to blend. Divide between ice cube trays and freeze at least 4 hours or overnight (the drink cubes will freeze only partially). Just before serving, empty trays into a large bowl and using a fork, break up cubes to loosen ice crystals (the ice will be slushlike). Spoon slush into tall stemmed glasses and serve immediately.
I contacted Disney back in 05 about the Red Hero sold in DS and they emailed the recipe to me. I think it was guest relations and it took a while before I heard back.
The line at the Cosmo Slushie booth was too long so we went to the permanent booth in France and got Grey Goose and Grand Marnier Slushies. Grey Goose won. I tried making the Cosmo ones at home using this recipe and ended up adding a bit more cranberry juice.
