## Abstract

Described herein is a cooking pot comprising (a) a food vessel that has an opening in the shape of an oval or a polygon with more than two sides, and (b) a lid sized and shaped to substantially cover the opening of the food vessel. According to some embodiments of the present disclosure, the lid has a ring protruding from the bottom face, concentric about a vertical axis of the vessel. When the lid is rotated about the vertical axis at an angle from a closed position, the protruding ring is positioned adjacent to an interior edge of the vessel, corners or vertices of the opening are uncovered, and corresponding corners or vertices of the lid hang over the vessel exterior.

## Claims

### Claim 1

A cooking pot comprising:
(a) a food vessel having a base and a wall extending upwardly from and about a perimeter of the base, wherein said wall forms an opening in the shape of an oval or a polygon with more than two sides; and
(b) a lid sized and shaped to substantially cover the opening of the food vessel of (a) when the lid is disposed in a first position relative to the opening, wherein
a bottom face of said lid has a ring protruding therefrom concentric about a vertical axis of the vessel, and
when the lid is disposed in a second position relative to the opening,
the lid is rotated about the vertical axis at an angle from the first position,
the ring is positioned adjacent to an interior edge of the opening,
corners or vertices of the opening are uncovered, and
corners or vertices of said lid hang over an exterior edge of the wall.
