Hello, I am having a family dinner with friends this weekend. I have ordered a 10lb brisket from a local farm. Now from what I understand it's about 1.5 hours per pound. I am picking the brisket up at 7am and wont be able to even marinade it until about 7:30 or 8:00am. I am picking it up the same day. Little upsetting as i'd prefer to marinade it over night but the butcher doesn't cut the meat until friday evening. Now my concern is I would like to at least get 4-5 hours of marindaing on it but if I do that nobody will be eating until much later. Is it possible to cut these into 3lb briskets and cook them at the same time? Will this cut down the smoking process? I am using an off set smoker that the heat is fairly easily maintained now. I have never smoked this much meat on it at once though. Any tips would be greatly appreciated!!
