1. A method for aerating a pasty product, the method comprising:
passing a stream of pasty product to be aerated through an apparatus, the apparatus comprising a housing extending in a longitudinal direction, the housing comprising an inlet for the pasty product to be aerated and an outlet for the aerated product, the apparatus comprising a plurality of sets of a rotor and a stator within the housing, the plurality of sets comprising a first set of a rotor and a stator and a second set of a rotor and a stator, wherein each of the plurality of sets of a rotor and a stator has complementary toothed rims oppositely orientated in the longitudinal direction, the apparatus comprising a drive shaft, the rotors of each of the plurality of sets set of a rotor and a stator being coupled to said drive shaft, the apparatus further comprising a gas injector for injecting, upstream of the first set of a rotor and a stator, a gas into the pasty product to be aerated, and the apparatus comprises an intermediate mixing chamber provided in the housing between the first and the second sets of a rotor and a stator, and the apparatus comprising a secondary product introduction member which protrudes into the intermediate mixing chamber so as to issue into said intermediate mixing chamber,
injecting via the upstream gas injector a gas into the pasty product stream at a position upstream relative to the first set of a rotor and a stator,
and injecting a secondary product via the secondary product introduction member into the intermediate mixing chamber.
