Abstract: A utensil for supporting microwave heatable material in a microwave oven is provided with a microwave responsive illuminator including a light source connected to a suitable antenna for receiving microwave energy and directing it to the light source. The oven has an energy distributor disposed for varying localized field intensities of microwave energy in the oven to promote uniform cooking of the heatable material. When the localized field intensity of the microwave energy adjacent the antenna rises periodically above a predetermined value, the antenna receives sufficient energy to cause illumination of the light source. When the localized field intensity falls below the predetermined value, the antenna receives insufficient energy for maintaining the illumination and the light source is extinguished. Thus, the energy distributor, in addition to promoting uniform cooking of the heatable material, also causes intermittent illumination or flashing of the light source to enhance attractiveness of the utensil.
