I would have ice in either, but more likely in orange juice. However, difficult child 3 got an ice shaver for Christmas and I've been using it to make my favourite drink, Greek-style iced coffee. It's mostly water, with a splash of milk. Coffee, lots of ice, and sugar (or sweetener) to taste. All shaken up until it's frothy, drink through a straw. Fabulous for quenching thirst, especially in summer (like now!)
An old boyfriend of mine used to drink ginger beer and milk, 50/50. Now THAT was sick! I'm so glad I never married him...
