Question: why is osso buco so expensive?
Answer: For Ossobuco, the shank is sliced thickly horizontally through the shank bone. Ideally, the slices are 1 1/2 inches (4 cm) thick, so they'll cook evenly. The dish has a rich sauce that comes from the marrow in the bones. ... Even in Italy, veal shank is so expensive now that butchers have come up with a substitute.
