a housing defining an interior cooking volume surrounded by insulated outer walls and at least one door that may open and close to provide access to the interior cooking volume;
at least one humidity blocking barrier subdividing the cooking volume into an upper, intermediate and lower cooking cavity having different temperatures and humidities;
a steam generator system introducing steam into selective cooking cavities according to an electric signal; and
a set of fans circulating air independently through the cooking cavities in isolation from the other cooking cavities;
wherein each cavity provides a separate heater and a thermal sensor; and
