1. A household mixer appliance comprising:

  • a mixing container with an inner surface and an open top;

    a drive arrangement; and

    a hook;

    wherein the hook comprises a proximal end, a distal end and a curved portion extending between the proximal end and the distal end, the proximal end having a sole attachment portion which when attached to the drive arrangement abuts a first inner surface portion of the mixing container inner surface, and is attachable to the drive arrangement via a through hole in the first inner surface portion such that the hook is rotatable around a horizontal axis of rotation within the mixing container when the hook is attached to the drive arrangement, the hook further having a distal-most point located at its most distant point from the proximal end, the distal-most point of the hook being offset from the axis of rotation to define a circular path as the hook rotates about the axis of rotation; and

    wherein the inner surface of the mixing container comprises a second inner surface portion comprising at least 40% of the mixing container inner surface having the shape of an oblate spheroid,wherein the inner surface of the mixing container comprises a third inner surface portion arranged diametrically from the first inner surface portion along the axis of rotation, the third inner surface portion comprising a flat surface extending radially inward from the second inner surface portion adjacent the circular path defined by the distal-most point of the hook towards the axis of rotation of the hook, andwherein the distal end of the hook is spaced from the flat surface by a separation distance, such that the curved portion of the hook can knead foodstuffs against the flat surface.
