I have tried many cooking methods and can't quite seem to get a pot roast to come out tender. I've tried using the cooking bags with liquid, cooking longer, cooking less, nothing seems to work. We end up eating the vegetables and throwing away about half the meat because its tough and tasteless. I've even tried using a slow cooker with not much better results. Just last week I finally had a pot roast come out nice and tender and juicy. I used a slow cooker, but I've tried that before. Perhaps its the meat? I bought the roast at Target. It was packed with seasoned liquid in a vacumn sealed bag. Perhaps its not my cooking after all? Perhaps the meat was dried out in the package? I've also been told the way meat is usually packaged--on a styrofoam board and wrapped in plastic--will dry the meat out. My mother never bought packaged meat. She always bought the meat in the case and had it wrapped in butcher paper only. I've also been told the vegetables used in a pot roast could dry it out. Be especially careful of the potatoes. Don't use russett or baking potatoes. They have a low moisture content and tend to draw moisture away from the meat. I used red potatoes with better luck. Well, does anyone have any cooking tips that could help?
