We had planned on cooking baby backs tomorrow for the 4th, but one of the outlaws has decided they'd rather have a slab of spares and brought over a slab. I normally spritz my baby backs during the cook instead of foiling them...I use a solution of apple cider vinegar, apple juice, liquid butter, and bourbon. I've never cooked spares, but know that most people subscribe to the 3-2-1 method. Does anyone have any experience spritzing instead of foiling? If so, how does it impact cook time?
