Abstract
A dish assembly for serving food includes a dish housing that defines a surface, upon which the food can be placed, and an inner compartment, a phase-change material within the inner compartment, and an electrically-conductive element inside the inner compartment and thermally coupled to the phase-change material. In a typical implementation, the phase-change material is adapted to melt in response to the electrically-conductive element being heated by an electromagnetic induction heater. The thus heated dish assembly can facilitate getting hot food to a table while it is still hot, and once at the table, keeping that hot food at least warm for quite some time, while it is consumed.
