An appliance for preparation of heated and stirred beverages and foods has a vessel and a base, with a mixing element rotationally driven within the vessel by magnetic coupling with a driving magnet array attached to an electric motor and covered by a cap. The mixing element is mounted on a rolling contact bearing assembly which fits upon a pin which extends from the cap through an opening in the vessel bottom. The vessel bottom is preferably a cast metal piece with internal cavities in which one or more heating elements are mounted whereby a liquid in the vessel is simultaneously heated and stirred or whipped. Electrical power to a mixing motor and heating elements is controlled either by a manually resettable thermostat, or by a self-latching relay controlled switching circuit which includes a blocking diode to supply rectified AC current to the motor for low torque start ups which will not decouple the magnetic flux drive of the mixing element.
