Place the steaming wand tip just beneath the surface of the milk. Start the steamer and after sometime, place the tip of the steaming wand, just above the surface of the milk, so that froth can be formed. If you are doing right, you may hear a light hissing noise. Once the milk gets heated to a temperature of around 150 to 160° F, turn off the steamer. Clean the steaming wand and keep the pitcher aside. The next step is to pull the espresso shot.
