Well, it looks like it's that time of the month or something for Jason Calacanis, who's in Los Angeles, with a crazy craving for a black and white cookie like the kind he used to have back in New York. Thanks to Nicole, you can always make an entire batch of them in your home kitchen, and if you're in LA today, you know that there's nothing like a rainy, gray day to hole yourself up in the kitchen with butter, sugar, and a nice warm oven.

However, there are some places in LA that have black and white cookies for which you might brave the rain-traffic - and these delis do have them - I called every single one on this list. But think: time and energy to bake-at-home vs. time and energy to brave horrible LA rain-drivers. You decide.

And when all else fails, just call the Black and White Cookie Company and have them deliver.

If people would only look to the cookie all our problems would be solved." - Jerry Seinfeld, Seinfeld (The Dinner Party)

Black and White cookies are one of the best things to ever come out of New York City, where they are so popular that they could be the city’s food mascot, with thin crust pizza running a close second. At first glance, the cookie looks relatively simple, but achieving Black and White perfection isn’t, well, black and white.

A real Black and White cookie has a thick, cakelike base. It is softer than a cookie and lacks the chew that a sugar cookie – which many bakers unfortunately choose to use as their base – would have. It also is not nearly as sweet as a sugar cookie, an important element because the cookie has to stand up to the sweetness of the icing on top without overwhelming the taste buds. The icing on the top of the cookie is a key element in the Black and White, not just because it creates the color pairing that gives the cookie its name. The icing – not frosting – is a relatively thin layer of chocolate or vanilla that is poured smoothly onto the cake-like cookie. A thick glob of overly buttery or sugary frosting would upset the balance of flavors – not to mention that it just wouldn’t taste that great on a cookie.
