A barbecue grill is a cooking device used for grilling food outdoors. It typically consists of a metal frame with a heat source, which can be charcoal, gas, or electric. The grill has a cooking surface made of grates where food is placed to cook. Barbecue grills are popular for preparing meats, vegetables, and other foods, often during social gatherings or cookouts. Grilling is a method that imparts a distinct flavor to food, often enhanced by marinades or spices. Many people enjoy using a barbecue grill for its convenience and the ability to cook large quantities at once. Safety precautions, such as keeping the grill away from flammable materials, are important to prevent accidents.
