Method and apparatus for baking food in a closed cooking space in which heated air is circulated

In an electric baking oven including a closed cooking space, and means for heating air and circulating heated air therewithin including a grill heater, the improvement comprising:

• temperature control means, coupled to said grill heater, for coupling said grill heater to full line voltage and intermittantly activating said grill heater during the baking of food within said cooking space so that the surface temperature of said grill heater is raised to a value ranging between 600.degree. C and 900.degree. C for a predetermined period of time and thereby generates a plurality of sequential heat radiation pulses within said cooking space of a predetermined amplitude, frequency, and duration to vary the temperature of the heated air within said cooking space in sawtooth fashion about a mean temperature value ranging between about 120.degree. and 160.degree. C and to bake said food and to brown the surface thereof with minimum of soiling of said cooking space.
