Chafing racks are designed to hold a food pan over chafing fuel for warming food at a buffet. They are a good alternative to chafing dishes and can be used with both standard metal food pans and disposable food pans. When choosing a chafing rack, the first thing you should consider is whether you will want to pay for high-quality, reusable food pans. If not, you can purchase a rack that is meant to go with disposable aluminum food containers instead. These are great for casual events, which is the ideal use for chafing racks. They are a more economical option than chafing dishes, but they get the job done almost as well. You can purchase a lid for your food pans to turn your chafing rack into an enclosed food-warming unit.
