Natural gas & propane


Gas grills are easy to light. The heat is easy to control via knob-controlled gas valves on the burners, so the outcome is very predictable. Gas grills give very consistent results, although some charcoal and wood purists argue that it lacks the flavors available only from cooking with charcoal. Advocates of gas grills claim that gas cooking lets you "taste the meat, not the heat" because it is claimed that charcoal grills may deposit traces of coal tar on the food. Many grills are equipped with thermometers, further simplifying the barbecuing experience. However propane and natural gas produce a "wet" heat(combustion byproducts include water vapor) that can change the texture of foods cooked over such fuels.

Added wood smoke flavor can be imparted on gas grills using water-soaked wood chips placed in an inexpensive "smoker box" (a perforated metal box), or simply a perforated foil pouch, under the grilling grate and over the heat. It takes some experience in order to keep the chips smoking consistently without catching fire; some high-end gas grills include a built-in smoker box with a dedicated burner to simplify the task. Using such smokers on quick-grilled foods (steaks,meat chop|chops,Hamburger|burgers) nearly duplicates the effects of wood and charcoal grills, and can actually make grilling some longer-cooked foods, such as ribs, easier, since the "wet" heat makes it easier to prevent the meat from drying out.

Gas grills are significantly more expensive due to their added complexity, and higher heat.  They are also considered much cleaner as they do not result in ashes, which must be disposed of, and also in terms of air pollution. Proper maintenance may further help reduce pollution. The useful life of a gas grill may be extended by obtaining replacement gas grill parts when the original parts wear out. Most barbecues that are used for commercial purposes now use gas for the reasons above.
