A chafing dish is a metal cooking or serving pan on a stand with an alcohol burner holding chafing fuel below it. It is used for cooking at table, notably in gueridon service, or as a food warmer for keeping dishes at a buffet warm.
Historically, a chafing dish (from the French chauffer, "to make warm") is a kind of portable grate raised on a tripod, originally heated with charcoal in a brazier,[1] and used for foods that require gentle cooking, away from the "fierce" heat of direct flames. The chafing dish could be used at table or provided with a cover for keeping food warm on a buffet. Double dishes that provide a protective water jacket are known as bains-marie and help keep delicate foods, such as fish, warm while preventing overcooking.
