What meat do you use for Ossobuco?
You can use all three, but for me the order in of preference, adding another option is:
Up until recently jfood would always place veal first. Over the last year he has been very disappointed in veal shanks that he has ordered in restaurants. They seem not to achieve the less than stringy and toughness he looks to avoid in osso.
He recent favorite is lamb shanks. Maybe it is his taste buds getting older but the flavor and texture of the lamb seem to go better. And if he wants beef, he just cannot find anything better than short ribs. They are the primo-top of jfoods current food choice for braised meats.
