<p>The problem of properly cooking food and handling heated food so that it retains a fresh-cooked taste, fragrance and appealing appearance is solved by apparatus that includes an inner wall means (15) defining an inner chamber (16) and an outer wall means (17) defining an air circulating passage (18) extending in a loop around the inner wall means. Louvered slots (28) with inclined fins (29) are provided in the inner wall means along said air circulating passage that are sufficiently narrow to confine the circulating air substantially to said passage without a significant amount of airflow in direct contact with the food in said chamber and at the same time arranged to permit moisture and heat to diffuse between the circulating passage in the inner chamber via said apertures to control the moisture and heat in the chamber and establish a substantially uniform temperature throughout said chamber. </p> |
