Just because the charcoal turns white, doesn't mean that it is time to cook. Placing hamburgers and steak on the grill as soon as the charcoal ashes will only sear the outside of the meat. When this happens, you will need to leave the meat on the grill longer to ensure the inside is cooked thoroughly. This could potentially leave you with a charred outside and undercooked inside or even a "hockey-puck." Follow these simple steps to ensure that your charcoal is ready for grilling and that your steaks and burgers come out grilled perfectly.
