This is my favorite chocolate chip cookie recipe. The New York Times did a big article on the perfect chocolate chip cookie, interviewing and sampling several famous chocolate chip cookies at various bakeries. Several tests were done; larger cookies (such as six-inch affairs) scored better, as did letting the dough age for 24 or even 36 hours (up to 72 hours). A small sprinkle of sea salt was also recommended. I usually make 3 huge cookies and divide the rest of the dough in half, wrapping it in saran wrap. Also, I've cheated a bit at this recipe and used plain flour instead of the two types of flour, as well as neglected sifting the flour. I don't have a paddle attachment on my mixer. I also usually use chocolate chips. You still achieve the very special taste, but the presentation is nicer when you follow the recipe exactly. From New York Times, July 9, 2008.
