A slow simmering braise is one of our most beloved cooking techniques at Highlands and Bottega. Shanks, veal or lamb lend themselves perhaps best of all to this method. This is the only meat that we do occasionally buy frozen (and then slowly defrost over several days in the refrigerator). Most butchers prefer to cut the shanks into 1 or 2-inch portions while they are still frozen. This is a rich dish, and following the Milanese tradition, we serve a saffron-flavored risotto and gremolata (a traditional garnish for osso buco made of chopped parsley, lemon zest and garlic).
