Sourdough Chocolate Chip Cookies

Browning the butter is what gives these cookies their deep, nutty flavor, which is a great base for the dark brown sugar and big chunks of bittersweet chocolate. The dough is simple to put together, but the chill time is a mandatory step - it's what keeps the cookies thick and chewy with crisp edges instead of spreading into thin wafers.
