Abstract: The present disclosure is directed to a variable vent cover for cooking vessels and comprises a bottom cover having an opening therethrough and a pair of upstanding outwardly divergent flanges diametrically opposed and spaced about the periphery thereof which cooperates with downwardly convergent flanges diametrically opposed and spaced about the periphery of a top cover with a minimum of clearance between the flanges on the bottom and top covers so that they can be rotated horizontally relative to one another to vary the vent opening between the flanges to communicate the opening in the bottom cover with atmosphere and which will assure that both covers will interlock to be vertically lifted simultaneously for placement onto or removal from a cooking vessel.
