2. Control The Temperature
HCAs begin to form at 325 degrees F. You want to make sure all meat is properly cooked while the temperature does not exceed 325 degrees F. Use a meat thermometer to make sure the ideal temperature is met for different types of food.
When you are done grilling and want to put the charcoal out, close all the air vents to snuff out the fire. Wait 24 hours, clean the charcoal ash from the grill, collect any unburned charcoal, and store it for next time.
