5.3. Milk Frothing (Steam Wand)
Create creamy milk foam for cappuccinos and lattes using the powerful steam wand.
- Fill a stainless steel milk frothing pitcher with cold milk (dairy or non-dairy) to just below the spout.
- Press the Steam button on the control panel. Wait for the steam indicator to become solid, indicating it's ready.
- Position the steam wand just below the surface of the milk. Turn the steam knob to release steam.
- Lower the pitcher slightly to introduce air for foam, then submerge the wand deeper to heat the milk. Continue until desired temperature and foam consistency are achieved.
- Turn the steam knob off and remove the pitcher. Wipe the steam wand immediately with a damp cloth to prevent milk residue from drying.
