Betty: "This tastes like food. Kind of like herbs de provence." (But she really liked it.)
Luke: "I don't want to drink anything that sounds like 'shart'."
If you can see past the 'shart' (and the prohibitive pricing - a bottle of this stuff cost me nearly 60 dollars) - Chartreuse will unfold its strange, age-old secrets to you. Its taste is distinctively herbal, not quite like any other liqueur you've ever had, and its history is old and rich. (Chartreuse has been made exclusively by French monks since 1605, and its formula is known only to two people. Take that, Coke.) Read all about it at the Kitchn, where yours truly expounds upon the mysteries and wonders of this mysterious and wonderful libation.
