ABSTRACT:
A pot lid adaptable to a cookpot for boiling down foods such as fish, meat and the like. The pot lid has a plate having a contour adaptable to the cookpot, and a cover detachably installed on an upper surface of the plate. The plate has a threaded hole at its center, openings for releasing steam and grooves which extend to the circumferential end of the plate. The cover has a diameter large enough to close the openings and a rod projecting downwardly. The rod has a threaded groove at its end portion with an ungrooved portion being left above the threaded groove. The threaded groove is engageable with the threaded hole of the plate. When in use, the ungrooved portion of the rod is slidably held within the threaded hole of the plate to permit a heated broth of the boiled foods to discharge from at least the openings.
