Mary from New York has been listening to our coffee episode with Marc Maron, where I proposed my idea that the only true iced coffee is one with coffee ice cubes. Mary favors using espresso, chilled with a bartender's flair, using a cocktail shaker:

Throw in your espresso, milk and sugar, add a handful of ice cubes last, shake, and strain over fresh ice. If you use whole milk (or sometimes even 2%), you'll even get a nice creamy layer on top. I realize this is technically an iced latte, but I'll be damned if this doesn't work with regular coffee, too. I always hate it when I get a traditional iced coffee, and the top of the glass is cold and watery, but the bottom is lukewarm and never gets cold because the ice is melted by the time you get there...My Shaker Method eliminates both problems, and serves up an icy cold treat! Try it. It will blow your mind.
