Main Page | See live article | Alphabetical index There are multiple varieties of grills, with most falling into one of two categories: gas-fueled and charcoal. Gas-fueled grills typically use propane gas as their fuel source, with gas-flame either cooking food directly or heating grilling elements which in turn radiate the heat necessary to cook food. Charcoal grills typically use charcoal briquets as their fuel source. The briquets when burnt will transform into embers, radiating the heat necessary to cook food. This article is from Wikipedia.
