A buffet warmer is a kitchen appliance designed to keep food at a safe serving temperature during events or gatherings. These warmers typically use electric heating elements to maintain warmth, ensuring that dishes remain appetizing and safe to eat. They come in various sizes and styles, often featuring multiple compartments for different dishes. Buffet warmers are commonly used in restaurants, catering services, and at home for parties. They help prevent food from cooling down too quickly, allowing guests to enjoy hot meals throughout the event. Many models also include lids to retain heat and protect food from contaminants.
