There are 2 categories of grill you can use for barbequing:
For sure, the traditional coal barbeque offers better results when it comes to flavor but at the cost of increased personal labor. If lack of time prevents you from getting involved with coal, it is better to opt for the gas solution. The careful selection of raw ingredients and the correct procedures will help you achieve results on a par to cooking with coal and, with far less personal effort.
Chose a barbeque with a large cooking surface and, preferably, with a lid, so that you can keep food warm even after cooking.
