You will need:
1 cup sugar
1 (.13 ounce) envelope unsweetened orange soft drink mix or flavor of your choice
3 cups milk
In a bowl, stir sugar, soft drink mix and milk until sugar is dissolved.
Pour into a shallow freezer container; cover and freeze for 1 hour or until slightly thickened.
Transfer to a mixing bowl, beat until smooth.
Return to freezer container; cover and freeze until firm.
Remove from the freezer 20 minutes before serving.
For the Silithid-tolerant I suggest Nerds candy to represent the sweet and crunchiness of the husks. And considering what this blog is all about, I think Nerds is appropriate addition.
