Ode to a café con hielo, a cooling pick-me-up on a hot day. So simple: just pour a freshly made cortado (espresso topped up with milk) over a couple of ice cubes sitting at the bottom of another glass, and stir. The ice cubes make a gentle cracking noise as the hot coffee is poured over them, which gives way to tinkling once they've melted a bit and are free to bob around in the glass. It's very hard to drink it slowly.
