Cooked food has been with us from the early days, since man discovered fire.
Probably, the first ever cooked food, eaten by man, was from the forest fires, which had burnt fruits or some animal.
As days passed, the method of cooking has undergone a drastic change, more so in the last century.
People today are very familiar with using gas grills for cooking food.
From basic wood and coal burning fires that were the mainstay for cooking food until about the beginning of the twentieth century, today the gas grills dominate.
Barring the developed countries, a majority of the people is still dependent on some or other form of wood, coal, and other fossil fuels to cook their food.
Their options are restricted on account of the higher cost and limited logistics involved with the access to cleaner fuels.
Gas is of course a relatively easy fuel to store and very easy to use under controlled conditions.
It is a relatively clean fuel too, in a couple of ways.
Firstly, there is no debris left over that the cook has to clean up, whilst the effect on the environment is not quite as damaging as other fossil fuels could possibly be.
There many other great benefits of course.
The cylinders which the gas is contained in can easily be moved around.
The gas grills themselves are often very portable too; which makes them ideal for taking away on camping vacations and road trips and so forth.
The functions on them are vast as well, with wind protectors, instant start and they also have exacting heat and flam control functionality.
This basic gas grills have at least one burner housed in a metal frame for support, and a control valve for throttling the flow.
Additional to this structure, there may be multiple burners, a spark generating arrangement to start the fire, protection mechanisms to safeguard against blowing wind, and so many more.
All mechanisms used in the gas grills are sturdy enough to last for many years.
When heading out to look for which product is best, it is always wise to make a checklist of what the requirements will be.
Many are intended only for backyard use for example, others for using when camping only.
There are also those that can be used in both environments.
Larger units with multiple burners are ideal for bigger groups, but will be more expensive.
Though most gas grills are very durable by design, the material can count for a lot.
For example, cast iron models are excellent for holding up against all but the very worst of conditions.
But in the salty air, say near the coast for example, they will be prone to rusting.
Stainless steel affairs will manage things such as this far better, and they will be lighter for increased portability, but will cost a little bit more.
All of these choices have a marked bearing on the cost of gas grills, so the decisions about the requirements need to be clearly demarcated between must have features and those nice to have.
With such a choice and availability of great deals though, there will be something to suit everyone.
