Chosen answer: A chafing dish is a large metal pan or glass container (either is called a "dish") that is used to serve hot food at a buffet. The dish fits into an elevated metal stand that has one or more holders on the bottom for small sterno containers. The heat from the lit sterno keeps food warm.
