Serve up warm party foods with our Buffet Food Warmers. These ethanol gel chafing fuel cans are perfect for a picnic party or any other celebration with a buffet. Carefully open the lid with a blunt object. Place the can in a designated holder on an upright surface before lighting. These cans burn for up to 2 hours and 15 minutes and should be used to keep food warm in a buffet. To extinguish, slide the metal plug upside down over the opening.
