A pressure interlock means to prevent release and opening of the cover under a potentially dangerous condition. The cooking apparatus is formed including a suitable open-top pot having a top cover unit secured to open and close the pot. Cooking oil is contained within the pot to a suitable depth or level spaced from the pressure cover unit. A pressurized deep oil cooker has a cover unit and includes a clamp bar pivotally connected to one side of a cooking pot. A mechanical hook unit couples a hook member on the free end of the bar to a pin. A plate cover has a D-shaped seal in a dovetail groove and abutts the upper edge of the pot. The cover is secured to the cam by a slotted connection permitting limited movement of the cover relative to the bar. A cam unit is coupled to the bar and has a rotating cam having a release position in which limited movement of the cover is permitted and a locking position which spreads the clamp bar relative to said cover to seal the cover and set the latch. A pressure sensitive piston in the cover moves into the path of a pin on cam operating handle to prevent to release with a pressure in the pot. An electrically operated pressure relief releases the pressure at the end of a cooking cycle.
