Abstract
A microwave egg cooking utensil having a microwave transparent container for water, a metal tray with at least one depression for holding the egg, and a metal lid. Both the tray and the lid are supported by a lip of the container such that there is a small gap between the outer perimeter edge of the tray and the inner surface of the lid. The combination of the tray and the lid provides substantial microwave shielding of the interior there defined; the separation of these metal parts prevents arcing therebetween. It is preferable that the edge of the tray be raised from the lip so that the small gap is not filled with condensation which would minimize the effect of the gap. The water in the container is heated to boiling by radiation of microwave energy. The steam heats the tray and the egg cooks by conduction rather than by microwave radiation.
