What piece of veal should I ask a butcher/meat shop in the US if I want to do stew dishes like "blanquette de veau" or "veau marengo"? Ideally, I should be using "tendron" which I think is equivalent to flank steak for a veal. But flank steak is "bavette" for beef, so maybe it is a different name. I think I could also use jarret, which is for the pork called ham hock I believe. Do I have any chance of finding these pieces? Do they have a proper name in US english?

Any other piece suggestions for veal-based stew dishes?
Veal and beef cuts are completely different, the terminology is not the same at all. With veal the tendron is part of the breast, which includes the foreleg and the front of what would be considered the flank on a full-sized animal, in other words the part that does the most work. The tendron cut includes the lower-front part of the ribs. As for what to ask a US butcher for I'm not sure, I'd ask for veal foreribs and hope that they get what I'm after. 

Here are some definitions that may help.
