Abstract: An oven with a fixed-elevation single-shelf for uniformly cooking three or more meat roasts to substantially equal, even, and uniform levels of doneness, centering them within an average 10.degree. F. parameter temperature zone under 212.degree.. Apparatus and procedures subject all of the roasts to substantially equal, even, uniform, and low density heat from naturally ambient (non-mechanically-induced movement) air.

Abstract: Disclosed is an apparatus for warming and humidifying food held within a food warming cabinet. Cool dry air within the food warming cabinet is drawn into an air intake chamber and exhausted through an opening in the air intake chamber by a fan. Air leaving the air intake chamber is forced through a tunnel. A humidifier pan having a reservoir full of water and a heating element are situated in the path of air flowing through the air tunnel. The air flowing through the tunnel is heated by the heating element and humidified by water evaporated from the humidifier pan. A porous material such as a sponge is placed in the water in the humidifier pan to increase the available surface area for evaporation. The porous material such as a sponge also acts as a wick to bring up the water from the humidifier pan to the porous materials' surface replacing the water evaporated by the forced-air passing over its surface.
