Locally known as l'oss bus a la Milanesa, these wine-braised veal shanks are a classic of northern Italian cuisine and one of Milan's most cherished signature dishes. Ossobuco is believed to have been prepared in local trattorias for centuries, although the first written recipe was found in Pellegrino Artusi's 1891 cooking manual La Scienza in Cucina e l’Arte di Mangiar Bene.
The word ossobuco translates to hollow bone — the cut of veal used for this dish is sliced horizontally through the bone and exposes the marrow, which is what gives the dish its buttery richness. Slow-cooked in beef broth until the meat becomes soft enough to cut with a fork, ossobuco is finished with a topping of gremolà or gremolada, a zesty herb relish made with mashed anchovies, minced garlic, parsley, and lemon zest.
