How much lump should I plan on to smoke my brisket? I am using the Smokeyokie sear method. My butt last weekend took almost 20 lbs of lump charcoal. This was maintaining my baby at 200* (except that 4am opps I missed the alarm going off, then I was at 117*) Is that about right or am i using just to much and should maintain the heat using air flow??? Also, what does one do about the ashes that build up underneath the lump charcoal? Sorry that would be two blonde questions for the day! Thanks, WINGS ON SAT FOR SURE! At least this game should be on the tellie out here! damn So Cal!
