A latté is a coffee made with foamed, steamed milk with shots of espresso added. To make a good latté:
 

1. Pour your milk into your desired mug until you have about 1.5 inches below the rim then transfer the milk to a steel steaming jug
2. Bring the steam wand up to pressure and ensure steam and not water is flowing before putting it into your milk
3. Hold the tip of the steaming wand just below the surface of the milk for a couple of seconds to form very fine air bubbles - you'll hear the tone of the steam change
4. Move the wand lower into the steam and slowly pass the jug up and down in the milk until the milk reaches between 65-70°
5. Pour the milk into the mug again - you should have around half a cm space left now (if you're adding flavoured syrups, do this now)
6. Place the mug under the bar and dispense a single shot of espresso through the foam on the top (if you're making a double-shot latté, use slightly less milk)
7. Take the mug out from the machine, clean the wand and dust with chocolate powder
