Charcoal is ready when mostly grey colored or if at night it's glowing red.
A good rule of thumb: The larger the meat is, the greater the distance from the coals.
Use a chimney to light your grill instead of lighter fluid. Lighter fluid affects flavor.
If you can't find beef rated USDA Prime, at least get the 2nd best option, USDA Choice.
Always make sure your grill is clean before you begin and after you finish.
Try wood chips soaked in Jack Daniels for a good smoky flavor.
When cooking larger pieces of meat over charcoal, put the coals on one side and the meat on the other.
Chicken needs to be rotated about every 4-6 minutes to cook well.
Push the coals closer together to make the grill hotter without using more coal.
Keep a water spray bottle nearby in case of flare ups.
