Abstract: A microwave oven food mixer comprises a body including a drive mechanism and a plurality of adjustable arms extending outwardly from the body. The body and arms are configured so that the body may engage the lip of a culinary vessel disposed on a turntable of a microwave oven, with the arms extended to engage walls of the oven. A mixing arrangement extends downwardly from the body and is arranged to be located in said vessel during use. The mixing arrangement includes a fixed stirrer and a rotatable stirrer. The fixed stirrer is secured to the body and arranged to pass adjacent an inner wall of the vessel. The rotatable stirrer is connected to the drive mechanism and arranged so that rotation of the vessel on the turntable with the arms engaging walls of the oven causes rotation of the rotatable stirrer.
