There is a big difference between using a gas grill and using a charcoal grill. Butane, propane, or natural gas is the source of heat for gas grills. Food cooks differently depending on the source of heat. This is due to different types of flames, different temperatures, and other factors. Some people believe you can only cook tasty food using charcoal grills. However, you can still make a great-tasting meal if you use gas grills properly. The best solution for choosing a gas grill is finding out if it will properly cook the foods you love grilling.
