Mix one packet unsweetened Kool-Aid mix together with granulated sugar. Add the milk, half & half and mix until dissolved. Pour mixture into a shallow freezer container.
Freeze for 1 - 2 hours until slightly thickened. Transfer mixture to a bowl and beat until smooth (I used a wire whisk).
Return to freezer container, cover and freeze 8 hours or over night. Remove 20 minutes before serving to soften slightly.
Recipe yields - 3 cups.
Cook's Note: I used orange and strawberry kool-aid for this recipe. I have also had a few people ask if 2% milk can be substituted for whole milk. I think it should still be creamy using 2% since the half & half is added.
