I like my iced coffee shaken, not stirred.
I think it tastes better when you add milk and shake it versus stirring. And it chills it because I like my iced coffee really cold. I've been mixing iced coffee from the fridge with milk and no sugar. I don't even adding sugar to my coffee although sometimes I may add some of the vanilla sugar my sister made me. Yes I still have some left Charlotte, I tend to hoard things I like.
