Abstract: A method for peeling potatoes with a food processor and a food processor which comprises for food preparation a detachable food preparation vessel, a heating element for heating a food in the food preparation vessel and a rotatable tool for mixing or chopping the food in the food preparation vessel. The method includes attaching a potato peeling disc having an abrasive structure on its surface from above to the tool which is located centrally at a bottom of the food preparation vessel to establish a manually releasable, rotationally coupled connection such that in operation the potato peeling disc rotates at the same rotational speed as the tool; addition of potatoes into the food preparation vessel from above onto the potato peeling disc; motorized rotation of the tool in a first direction of rotation and peeling of the potatoes with the potato peeling disc inside the food preparation vessel.

Abstract: A potato peeling disc for peeling potatoes has a central opening formed by an inner contour of the potato peeling disc. A surface of the potato peeling disc comprises a plurality of teeth. The teeth have an orientation such that potatoes are peeled by the teeth by rotating the potato peeling disc in a first direction of rotation about a central axis which is coaxial with the central opening.
