When doing a low 'n slow cook, I have always lit the lump in one spot in the center. I figured if I light two or three areas it would be harder to control temp and may not conserve lump as well. [p]The other day, I saw a post where they always light at least 3 areas to avoid center burnout. I assume that means the fire burns only in the center and goes out, leaving all the lump around the outside unburned. Has this happened to others much? Which approach do you think is the most foolproof, all things considered?
