I am having close to 20 people over this weekend and am going to smoke a brisket. Due to the width of my smoker I have to have the brisket cut in half and smoke on two racks. Here's the question, if I smoke for 1.25 hours per pound, do I lessen that because it is in two pieces or do I consider the entire weight? Sorry for the elementary question but I want to get it right for sure. Thanks for your help.
