Help. I prepared ChefRD's Hot Wings for the second time -- both times with excelent results. However, both times I was only able to get fire over about half of the grill surface. I do not have fire around the outer portion of the grill, and dthe wings in that area does not cook until I place them in the middle. My question is - should I use more pieces of "fire-starter" around the outer edge of lump? I used three pieces this time, but I guess they were still more toward the center of the charcoal. About how many pieces should I use? and how should they be placed? Thanks.
