Chafing dishes are specialized food service equipment used to keep cooked food warm for extended periods. They typically consist of a large, shallow pan that holds the food, a water pan underneath to create steam, and a heat source, often fueled by canned heat or electricity. These dishes are commonly used at buffets, catering events, and parties. The design of chafing dishes allows for easy serving and maintains the food's temperature without cooking it further. They come in various styles and materials, including stainless steel and glass, making them both functional and visually appealing for any dining setting.
