Place the ice in a bowl, combine the milk and vanilla and mix! And then ENJOY IT! (You could use peppermint extract too if you'd like a different flavor. I suppose you could try chocolate syrup although I never have.)
Of course, I also had someone tell me I shouldn't eat it because of the pollution in the snow but I figure I eat veggies that are grown in goodness knows what and then I eat meat from the store where they inject who knows what. (we are trying to eat local but still you never know)
But it is yummy and cheap. And something hopefully your kids remember making and eating just I like I remember!
