I’ve tried this, with less desirable results. I used a beef chuck roast, cut off most the fat, about 1kg. Sliced across the grain, about 1cm thick. Sprinkled meat with 1capsule of NOW brand bromelain. Vac packed, cooked at 53C with polyscience circulator. The result was meat mush. Much of the meat broke down into a mahogany colored paste. The taste was fine, very savory, but the texture (and color) was disgusting (and I have a strong stomach). Any ideas what happened? I have checked the temp with a lab thermometer, less than .1C off. The bromelain from NOW foods was fresh; just opened container.
