ABOUT OUR PROPS A welcome addition to any block party, the “black and white” cookie also clearly reflects color blocking. A New York institution, black and white cookies are humongous—measuring at least five inches across—New Yorkers consider the miniatures a legal offense—and consist of a cake-like vanilla/lemony base. But it’s the icing that makes the difference. One half is covered in chocolate; the other half, vanilla. Featured on a “Seinfeld” episode, these cookies are available in any reputable New York deli and also in such gourmet temples as Zabar’s and Dean & Deluca. To make you own, check the Internet for an endless selection of “the perfect recipe.” | |
