Had this while dining out so made it ourselves tonight. Put some water ON your glass mug and put it in the freezer so it is frosty and ready for you. The half and half is the same size as you can get at the gas station or restaurants that come in those tiny cups. And if you want to use diet soda or vanilla mixed into vodka, go for it. After looking at Chef#169430 review, notice that you should not use fat free creamer as it won't mix in nicely.
