ABSTRACT:
A portable griddle stove has two non-stick cooking surfaces, either of which can withstand being on the underside of the cooking surface in use and the heat applied to the underside surface. A heat shield and heat diffuser control the temperature applied to the underside of the cooking surface by providing radiant heat to the center portion of the cooking surface and cooling the combustion gas diffused to the perimeter of the cooking surface. Secondary air provided through openings in case the and heat shield assist in cooling the combustion gas.
