Claim 9:
10. An electric heating element, comprising:
an electrically resistive inner heating element including an inner coiled heating portion and first and second cold legs extending from the inner coiled heating portion for connection to an electrical power source;
an electrically resistive outer heating element including an outer coiled heating portion positioned in a common plane with and around the inner coiled heating portion, the inner and outer coiled heating portions defining a working surface for receiving a cooking utensil thereon, the outer heating element including third and fourth cold legs extending from the outer coiled heating portion for connection to the electrical power source, wherein
the first, second, third and fourth cold legs are under the common plane and extend radially past an outer diameter of the outer coiled heating portion, and
the third cold leg is positioned adjacent to and above the first cold leg and the second cold leg is positioned between the third and fourth cold legs;

first, second, third, and fourth electrical conductors extending from the first, second, third and fourth cold legs, respectively, wherein the first electrical conductor is connected to the third electrical conductor and the second electrical conductor is connected to the fourth electrical conductor, wherein the third and fourth electrical conductors are configured for engaging with an appliance electrical receptacle having a single pair of electrical conductor receiving ports;
a medallion positioned below the working surface and inside the inner coiled heating portion; and
a thermostat positioned in electrical series along the second cold leg in proximity to the inner coiled heating portion, the thermostat configured to detect an upper predetermined temperature and a lower predetermined temperature and selectively open and close an electrical circuit to cycle off and on the inner coiled heating portion while the outer heating element remains electrically energized.
