ok, heres the deal. i bought me a 8.5# butt today. just rubbed it down with jeffs rub (first time using it, and just mixed it together). plan on cooking it tomorrow (weather permitting, sunday if not tomorrow) at 225-240 for 12-13 hours and splashing it with apple juice/rum mix. questions.... -do i cook it with the fat down or up? -i also just mixed up the finishing sauce. my pepper is settling at the bottom, and my pepper flakes are at the top (in my bottle.) is this a problem? give me your input.
