A specialty of New York delis, black-and-white cookies got some extra attention a few years ago when they were featured on an episode of Seinfeld ("Look to the cookie!" Jerry shouted). But these unusual delights have long been a culinary curiosity. Also known as half-moons, the cookies are made using the basics: flour, butter, sugar, eggs, milk, baking powder, salt, and a touch of vanilla and lemon. Then they're covered with sweet frosting, chocolate on one side and vanilla on the other -- thus the simple, descriptive name. (Seinfeld suggested that the proper way to eat one was to munch up the middle so that both colors were included in every bite.) Although Denver has always had problems getting authentic New York food, the New York Deli News delivers: These homemade black-and-whites are authentic six-inch, melt-in-your-mouth monsters. At $2.75 apiece, the cookie's large enough to split with a friend; the only problem is deciding who gets which color.
