one thing I think we should also mention is using a way to direct air flow
On some cooks I like to put foil over the parts of the cooking grates that do not have coal/baskets over them, and sometimes I cover the side vents on the baskets. it is all about experimenting for cooking that item.
Such as beer can chicken, I cover the bottom and have 2 baskets half full so I get 350 degrees, I also block the inside vents of the baskets as the chicken is sitting between the baskets. I am trying to direct airflow.
And as we know, we want airflow going to benefit an even cook.
Maybe I am a bit anal, but I keep notes, I count coals, I try to figure out how to improve a cook.
Yes that means that I do better on some cooks than others, but I can always pull out my best method to show off my grilling.
Part of being a grillfella is striving for the best.
Have fun
