A cooking pot lid provides a continuously variable amount of venting (and stirring of ingredients, when desired) and includes a fixed lid component including a plurality of spaced-apart openings, a rotatable shaft disposed through a central aperture of the fixed lid component in a manner such that the rotatable shaft is free to rotate with respect to the fixed lid component; and a rotatable lid component that is attached to the rotatable shaft. The rotatable lid component includes a plurality of spaced-apart fins for alternately covering and exposing the plurality of spaced-apart openings in the fixed lid component to provide the continuously variable venting. Stirring blades may be attached to the rotatable shaft in a manner such that the stirring blades rotate with the shaft.
