Abstract
An apparatus for cooking food with infrared radiation includes an infrared energy emitter for emitting the infrared radiation, and a grid in close proximity to the infrared energy emitter. A first side of the grid can be for supporting the food at a position so that at least some of the infrared radiation will cook the food. A second side of the grid can be sufficiently close to the emitting side of the emitter for substantially restricting any airflow in any space between the second side of the grid and the emitting side of the emitter. Partitions of the grid can operatively segregate the emitting side of the emitter into segments, which can provide a substantially uniform distribution of infrared radiation.
