10. A pressure cooking appliance, comprising:
a cooker body;
a lid comprising:
an upper lid portion;
a lower lid portion, the lower lid portion being constructed and arranged for lockingly covering the cooker body of the pressure cooking appliance to form a pressure-withstanding cooking chamber therebetween;
wherein the upper lid portion is disposed above the lower lid portion and substantially covering the lower lid portion;
the upper lid portion comprises a main lid body and a removable cover;
the main lid body comprising an opening portion formed substantially at a central portion of the main lid body for exposing the lower lid portion or at least a portion thereof; and
the removable cover being removably attachable to the opening portion and operable to expose at least a portion of the lower lid portion for accelerating the cooling of the cooking chamber, thereby speeding up a wait time for safely opening the lid;
wherein the portion of the lower lid portion exposed by removing the removable cover is a surface absent openings through the lower lid portion.
