The Osso Buco is the shank (forearm) of the animal and includes a marrow bone at its center. This hard working muscle starts tough, but the right treatment will yield a tender and decadent final dish.
Low and slow is the name of the game. To achieve the desired fall-off-the-bone perfection, you'll need to cook to 180°F, and keep it there for a few hours. The long cooking time allows connective tissue to break down, and lessens the chance moisture will escape. When slow cooking meat, you want to layer your flavors by braising using REAL stocks/bone broths along with fresh herbs. Finish your deep braise with vinegar or fresh citrus to brighten all of those wonderful flavors.
