I have a 1ft by 1ft (roughly) fire box. Currently i' using the pyramid method for building th charcoal (building a pyramid, and then only igniting the top layer of charcoal so it burns down). I can get about a temp of 240F Avg. with it. Anybody know a god way of making your fire hotter? (I try to get the heat to bounce aroudn between 220 and 300 as I usually cook Ribs and a beer can chicken in the same chamber.)
