1. A heat retentive server comprising:
a body having a chamber, an upper shell, and a lower shell, the upper shell and the lower shell connected to one another, the chamber being defined between the upper shell and the lower shell;
an induction-heatable member positioned in the chamber; and
a buffering material configured to provide a predetermined conductive heat transfer from the induction-heatable member to the body such that the server is configured to cooperate with an insulated cover covering a surface of the server with a dish and food placed upon the dish between the insulated cover and the server to keep the food at a temperature above 140° F. for one hour after the food and the dish are covered with the food being at a temperature of about 165° F. when placed on the dish and the dish being about room temperature when placed on the server, the buffering material comprising:
a lower insulating section positioned between the induction-heatable member and the lower shell; and
an upper buffering section positioned between the induction-heatable member and the upper shell, the upper buffering section being less insulative than the lower insulating section.
