Which of the following statements is true about a kettle charcoal grill?

A kettle charcoal grill is designed to allow for versatile cooking techniques, and one of its key features is the ability to adjust the airflow by manipulating the vents. This adjustment is crucial because it directly influences the temperature inside the grill. By opening the vents, more oxygen enters, which can increase the temperature, making it suitable for high-heat cooking methods like searing. Conversely, closing the vents reduces airflow, thereby lowering the temperature, which is beneficial for slower cooking processes such as smoking or roasting. This versatility in temperature control is a fundamental advantage of kettle charcoal grills, enabling grillers to achieve a variety of cooking styles efficiently.
