On the top model of PrimaDonna Elite there's an extra beverage experience: the hot chocolate function .
The chocolate drink texture is created by a unique system. An aerator (that looks like a small propeller) sits at the bottom of the carafe and is activated by a magnet located in the drip tray area. This mixes the milk and chocolate powder together adding air and volume to it while hot steam is released into the carafe via the tube - the results are a delicious and a sumptuous drink!
The carafe can then be removed from the machine and the hot chocolate poured in a favourite cup.
See the below 'How To' video, it shows you exactly how it should be done !
