New Yorker's black-and-white cookies
To me, the black-and-white cookie is as iconic to New York City as bagels, egg creams and cheesecake. Their iconic silhouette helps them stand out at many a bakery or bodega's counter, though the modern version uses fondant rather than frosting to avoid smearing. If you head to Manhattan's Yorkville neighborhood, you can try one of its forefathers at Glaser's Bake Shop, open since 1902.
