2.3 Frothing Milk
Move the steam wand to a suitable position over a milk pitcher filled with cold milk. Press the Menu button to select the STEAM function. When ready, press the Start/Stop button to begin steaming. A countdown will appear on the LCD screen. Hold the frothing jug at an angle so the top of the steam wand is just below the surface of the milk to create velvety microfoam for lattes and cappuccinos.
