I am a new owner of a large BGE and I am loving it so far! This weekend my family is having a party with a fair amount of people coming over, and I would like to cook both a whole brisket and a boston butt at the same time on the large BGE. I am looking to cook both a 13lb whole brisket and a 7 to 8lb boston butt. My question is whether I can cook these at the same time on one cooking level or not? I do not yet have either an adjustable rig or a grill extender. I am starting to worry that I need to go buy another level if I want to cook these two meats at the same time. I know that if I used multiple/tiered levels I would put the brisket on the bottom level and the boston butt on the top level, but I would like to cook it all on one level if possible. Can you let me know your experience with this? Thanks for any advice you can give to a new EGGhead!
