A steam table is a piece of kitchen equipment designed to keep food warm for extended periods, commonly used in restaurants, buffets, and catering settings. It uses steam generated from heated water in a reservoir beneath the food pans to maintain the temperature of the food. The table typically features several compartments where food pans are placed, ensuring that dishes stay hot and fresh without direct contact with a heating element, which can prevent overcooking or drying out. Steam tables are essential for serving hot food in large-scale operations.
