I don't know if your friend does Butts and Brisket in the Sous Vide but, for me, it works great for smaller cuts of meat like Steak, Chicken, and Pork Chops. Any meat you cook in a Sous Vide will need a searing after coming out of the water bath as it looks bland at that point. Last year I played with it a lot and decided that if I wanted BBQ I would just do straight BBQ. I tried smoking meat for 6 hrs. to get a lot of smoke and bark on it and then finish in the Sous Vide. Took a long time, timing required planning far ahead, the meat was moist, tender and tasty but the bark was soft. I tried Sous Vide first and then smoke. Moist, tender, and tasty but very little smoke flavor and weak bark. I even tried Smoke, Sous Vide, and smoke. Excellent results but way too much work for me. I did Brisket, Pork Butt, St. Louis cut Ribs, and Pork Steaks. Some folks who Sous Vide Butts, and I did, finish them in a 400° oven. I finished in the smoker. The cooler, pictured above, was modified to handle big cuts of meat and large quantities of veggies. I hope that's clear enough.
