Snowfall Ice Cream, With Variations

First, you want to gather a couple quarts of untouched new-fallen snow. If you're expecting snow, you can put out a receptacle to gather it for you. Immediately, gingerly mix in about a half a cup of ice-cold whole milk or half-and-half into which you've dissolved a quarter cup of sugar, and stir in a teaspoon of vanilla extract. And that's it: no freezing, no churning.
