Abstract: The present invention is directed to a microwavable container for cooking various food article, particularly seafood such as shrimp, lobsters, king crab legs, mussels, clams, and fillets of fish. The container is made of a single piece of molded plastic having a top portion and a bottom portion of approximately equal dimensions. The top and bottom portions have a surface and continuous walls extending from the surface. Around the edges of each wall is a flange, one side of which forms a hinge. The hinge is dimensioned to create a gap between the top portion and bottom portion when the container is closed to vent excess steam generated during cooking. The flange also includes an attachment means for securing the top and bottom portions together in a closed position. The bottom surface and walls of the container include raised ridges and ribs creating passageways allowing steam to circulate around the food articles, enhancing the cooking of seafood in a microwave oven.
