A chimney starter is a simple tool used for lighting charcoal quickly and efficiently. It consists of a metal cylinder with a handle, designed to hold charcoal briquettes. By placing crumpled newspaper or other kindling at the bottom and filling the cylinder with charcoal, users can create a direct airflow that helps ignite the charcoal evenly. To use a chimney starter, you light the newspaper at the bottom, and the flames rise through the charcoal, heating it from below. This method eliminates the need for lighter fluid, resulting in a cleaner and more flavorful grilling experience, making it popular among grilling enthusiasts.
