A system for maintaining foods warm including an exterior container with a lower generally horizontal flat support surface and upstanding side wall with an open top, the open top having a receipt area including a generally annular flat surface. Also included is an interior container that is adapted to receive food and which has a lower generally horizontal flat surface and an upstanding side wall receivable within the exterior container. The interior container has an outwardly extending flange with its upper extent receivable in the receipt area. A thermal retention region is provided between the interior and exterior containers and includes a generally flat horizontal circular region between the lower surfaces of the interior and exterior containers and extends upwardly between the side walls of the interior and exterior containers. The thermal retention region has an essentially common thickness throughout its entire extent. The thermal region has indicia to indicate the extent to which a thermal medium such as hot water is placed within the exterior container to ensure that when the interior container is placed therein it will rise to an appropriate level.
