1. A method of performing a frothing cycle for milk in a frothing apparatus container by injecting steam mixed with air provided by an air pump into the milk in the container, the method comprising the steps of:
1a) disabling the air pump;
1b) determining a back pressure of a wand having a distal end that is submersible in milk in the container, the back pressure being measured in an air ingress flow path from the air pump prior to mixing with steam;
1c) determining a pressure set point, dependent upon the determined back pressure and a desired pressure profile, to be established by the air pump; and
1d) enabling the air pump at a pump power dependent upon the determined pressure set point.
