My perfect chocolate chip cookie is crispy on the outside and gooey in the middle, with just the right amount of sweetness from the chips and a toasty molasses flavor from the brown sugar. But the most important—and elusive—requirement is fresh-from-the-oven meltiness. I rarely find a cookie that embodies more than one of these characteristics, let alone all of them. But then I flew Midwest Airlines. When I booked my ticket I thought I was just getting a cheap fare; who knew I would also find killer cookies a mile high? Luckily for me I had a connecting flight, which meant that I got not two but four warm, fresh-baked cookies. And yes, I ate them all.
