Cooking on a grill is a popular way to prepare food. Broiling, barbecuing, and searing are all methods of cooking on a grill. Broiling is the process of cooking food directly under a heat source, such as an open flame or electric heating element. Barbecuing is the process of cooking food over an open flame or hot coals. Searing is the process of quickly cooking food over high heat in order to create a flavorful crust. All three methods are used to cook food on a grill.
