Cooking stone apparatus with rotatable cooking surface

A cooking stone apparatus for use in ovens and on barbecue grills, comprising:

• a bottom support plate having a top surface,
• a circular cooking stone having a bottom surface and a perimeter edge, and
• a bearing ring disposed between said circular cooking stone and bottom support plate such that the circular cooking stone is rotatably supported on the bottom support plate by the bearing ring, wherein:
• the top surface of the bottom support plate has an indentation sized to fittingly receive the bearing ring, said indentation having a depth such that the height of the received bearing ring extends above said indentation:
• the bottom surface of the cooking stone has a circular indentation sized in correspondence with the bearing ring wherein, when the cooking stone is placed over the too of the bottom support plate, the circular indentation in the bottom surface of the cooking stone can be registered with the bearing ring so as to positionally fix the cooking stone over and in spaced relation above the bottom support plate, wherein the cooking stone can be rotated on the bearing ring, and
• the cooking stone has a plurality of engagement points around its outer perimeter such that, when the cooking stone is placed over the bottom support plate on the bearing ring, application of a tangential force at any one of said engagement points by a user using a hand tool causes the cooking stone to rotate on the bearing ring about the perpendicular axis of the support plate.
