I decided to try the Mississippi Roast smoked than finish in Sous Vide. After almost 5 hours at 225 roast was only up to 145 so pulled it and put into Sous Vide at 170 for 24 hours. The sous vide bag leaked a little bit. Made gravy from sauce which was a mistake. Was really salty. Made sandwich next day. Still a little salty but not to bad. Don't think the Mississippi was meant to be cooked that long. The polenta was really good as where the ribs.
