Chicken Basil, or Gai Pad Gaprow, is one of the classics of Thai food and is surprisingly easy to make. It is popular among the Thais and known as a no-brainer dish. In Thailand, when you are in a strange town and a strange restaurant, you know that you can always order Gai Pad Gapow and it will probably be decent. It's a simple dish that any restaurants know how to make it right.
You know you've made Chicken Basil right when the heat from the chili peppers plays just under the flavor of the gaprow and the fish sauce. Don't be afraid to use what seems like an excessive amount of gaprow leaves - they make the dish.
