Abstract: An axially collapsible cooking vessel comprises a flexible body having plural circumferentially extending reduced thickness areas spacedly arrayed between an upper peripheral edge and a bottom edge that provide for nested folding of the flexible body axially inwardly and downwardly upon itself; a heat conductive base that is interconnected with a bottom peripheral edge of the flexible body in a fluid tight engagement therewith; a heatsink structurally interconnected to a bottom surface of the heat conductive base, the heatsink having an annular shaped radiator and a circumferentially extending shield extending about the annular shaped radiator; and a removable lid releasable engageable with a top opening defined by the flexible body.
