Gremolata is the classic garnish for osso buco, a northern Italian veal shank dish. It is a fragrant mixture of lemon zest, parsley and garlic, sometimes with added bread crumbs. Here it does a nice job of lifting the flavor of sweet potatoes. This is a lovely dish to serve alongside roast chicken or pork.
Substitute orange zest - a flavor very compatible with sweet potatoes - for the lemon.
