What is the purpose of the fire from the catering sterno during an event?

The primary purpose of the fire from a catering sterno during an event is to keep food items hot. Sterno, which usually contains a flammable gel, is commonly used in buffet setups and catering services to maintain the temperature of food over an extended period. This is particularly important for safety reasons, as hot food needs to be kept at a certain temperature to prevent bacterial growth and ensure it remains safe for consumption. While the other options might pertain to other types of heating or lighting sources, the main function of the sterno in a catering context is specifically geared towards food temperature maintenance. This allows guests to enjoy their meal at the ideal warmth, enhancing the overall dining experience.
