Would appreciate any insights on sous vide chuck roast. I've followed the 132 deg for 24 hrs and 48 hours. Felt like the tough bits were not quite gone at 24 hrs. At 48 hours it was absolutely beautiful, (looked like prime rib or a loin roast), but my daughter commented, "Its nice, but I like to chew my beef." It wasn't mushy, but the meat was a approaching being soft... Not perfection. So, has anyone found the perfect combination of time and temperature to melt the toughness, but keep the meat firm with a good "chew"
