Used a chuck roast which I normally would braise until tender from a steer I alfalfa and grain fed for fifteen months. Made a Jamaicam jerk seasoning which is vinegar, soysauce, green onion, garlic, cinammon, allspice, nutmeg, salt and couple other things, Cut all the sinew, fat and bone away. Then put the Jaccard to it until it was twice the size it was before I started. vaccuumed sealed it for about a week and pulled it out to see what I had. Handled it and it felt felt like a stretchy piece of shoe leather. Decided to cut in into stir fry chunks and cook it with veggies and rice. It was palatable but not something I would pursue again....
