1. Cooking apparatus comprising:

  • an enclosure having a food support for an article of food to be cooked, and a fuel support for solid fuel, the supports being having food supporting and fuel supporting areas respectively, said areas being displaced from each other sufficiently that cooking of a food article on said food supporting area by fuel on said fuel supporting area can take place, at least in substantial part, as a result of contact between said food article and hot gas produced by combustion of said fuel;

    an impeller arranged to cause air to flow from the exterior of said enclosure into the interior thereof, and to impinge upon solid fuel on said fuel supporting area;

    an electric motor arranged to operate the impeller;

    a first temperature sensor for sensing the temperature of the atmosphere within said enclosure in the vicinity of an article of food on said food support, and providing a first output signal;

    a second temperature sensor for sensing the internal temperature of a food article on said food support and providing a second output signal;

    a controller, responsive to said first output signal, for controlling operation of said electric motor, said controller causing the impeller to increase the flow of air into the interior of said enclosure with decreasing temperature of said atmosphere and to decrease said flow of air with increasing temperature of said atmosphere, whereby said atmosphere is maintained substantially at a set point temperature;

    said controller being also responsive to said second output signal for reducing said set point temperature as the internal temperature of said food article increases.
