Which of the following is not a cut taken from a cushion of veal?

Osso bucco is indeed not a cut taken from a cushion of veal, as it specifically refers to a dish made from cross-cut sections of veal shank, which includes the bone and marrow. This dish is traditionally made from veal shanks that are typically obtained from the leg of the animal, rather than from the cushion, which is a section more associated with cuts like the veal tenderloin, veal chop, and veal rib.

When considering the other options, the veal chop is a cut that comes from the rib area and can include the bone, while veal tenderloin is taken from the loin area, specifically from the muscle that sits alongside the spine. Veal rib is also directly sourced from the rib section of the animal. All of these cuts are indeed derived from the cushion of veal, highlighting the specific nature of osso bucco as a distinct preparation rather than a traditional cut of meat from that part of the animal.
