ABSTRACT:
A ventable steam cover for a culinary vessel includes a curvilinear wall forming an enclosed chamber to provide a modified convectional cooking atmosphere. The curvilinear wall has an annular seating rim for engagement over a range of different sizes and types of cookery. A flange depending from the annular rim centers the steam cover over the mouth of the vessel. A handle assembly incorporates a valve plate rotatably mounted for selective displacement to release the vapor and for introducing a flavor ingredient. A hooded vent deflects the escaping gases away from a hand engageable knob portion.
