Abstract: A lid is adjustable for fitting over various sized pots. Fastening structure is provided for attaching the lid to the pot. A motor is configured to attach to the lid. A stirring apparatus is adapted to be disposed within the pot when the lid is attached to the pot. A drive mechanism is attached to the motor and to the stirring apparatus, and is configured to rotate the stirring apparatus. The lid includes a substantially disk shaped central support structure which supports the motor. An aperture within the support structure is configured for the drive mechanism to extend there-through. A series of overlapping leafs are disposed annularly about the support structure and are hingedly connected thereto. The drive mechanism includes a drive shaft attached to the motor, and a nested structure which comprises an elongated sleeve and an elongated piston which is slidable within the sleeve. The nested structure includes structure to restrict the piston from rotating relative to the sleeve.
