Abstract: A cover for microwavable containers is formed of a composite of textile materials which enhance microwave cooking. One layer provides insulation to hold heat within the microwavable container, while another retards splattering. The device allows steam ventilation from the container without the requirement of lifting a corner of the container, or otherwise taking steps to provide ventilation. The cover is machine washable. The cover has an elastic perimeter which allows the cover to be placed over the container, with the elastic holding the cover in place against the container, and allows the cover to fit a range of variously sized and shaped microwavable containers.
