This is the recipe if you've been trying to imitate the one you had on Carnival Cruise Lines. Serve in chilled soup bowls, and garnish with fresh sliced strawberries.
2 cups frozen strawberries
2 cups milk
1 cup heavy cream
½ cup sour cream
2 tablespoons white sugar, or to taste
Puree strawberries, milk, cream and sour cream in a blender or food processor until smooth. Stir in sugar to taste. Chill 8 hours or overnight in refrigerator before serving.
