My only suggestion, make sure you use wood charcoal and take your time. IMHO, using petroleum based charcoal (i.e. kingsford) is no better than using a gas grill and in many cases worse.
Kingsford was the name of one of Henry Ford's sons-in-law. Henry had a pile of oak scraps from the off-fall from cutting top bows from Model As. He was the original enviornmentalist/cheapskate and financed a charcoal plant and let Kingsford run/manage/own it. All the charcoal was made from the oak..............it was good honest charcoal. Then the Clorox Company bought it and it is now made from petroleum sludge and sand. Yeah, it lights, but it sucks.
I use lump charcoal or briquettes made from hardwood. You will not find the word "hardwood" anywhere on a bag of Kingsford.
