The traditional frother can take a bit of practice. First of all, ensure the milk is fresh and at refrigerator temperature. Use a stainless steel carafe so you can feel the temperature of the milk.
In order to make perfect cappuccino dip the tip of the traditional milk frother into the milk. When the appliance is ready carefully rotate the steam valve until it is fully open. This will froth the milk.
Next, when you have achieved enough froth, use your free hand to feel the carafe temperature. Alternatively use a thermometer. Never heat the milk over 70 degrees as this will affect the quality of the frothed milk. It is also possible to froth milk in this way for excellent hot chocolate and malt drinks.
Each time you finish milk delivery allow a little steam to flush through the frother, and remember to clean the removable nozzles thoroughly with a little washing up liquid. Rinse and dry thoroughly before reassembling.
