Diet root beer and cream or half and half (local dairy, please). Y'all, this is a damn root beer float. At least it sure starts to pass as one when you haven't had the real thing in several sad, deprived years. And even though I'm trying to slowly but steadily ditch my diet soda habit, I'll still have one of these if/when a craving for sweetness starts to eat me alive. Hope you think it's as good as I do!
