I'm a hobbyist cook at home and am new to the forums (love), so please forgive the amateurish question but I've searched and can't find a good answer. I have tried cooking cuts of bottom round steak, chuck and a whole lamb shoulder for the prescribed times and temps as described in Modernist Cuisine, and each time a large amount of liquid is liberated into the bag. The meat correspondingly shrinks and comes out very dry, not the moist succulent things that got me interested in sous vide in the first place. They are also overcooked. Chuck and bottom round were about 1.5" thick, cooked at 133F for 24 and 12 hrs respectively. Seasoned only with some pepper. 6lb lamb shoulder cooked at 143F for 72 hrs - HUGE amount of liquid in bag at the end. Seasoned with sliced garlic, olive oil, fresh rosemary and sprinkle of salt per the recipe. I'm using a Crock Pot / Sous Vide Magic PID combination with bubbler. Accuracy of temperature verified with a digital cooking thermometer. HELP. I must be missing something.
