I don't care how you spell it. You can spell it Choffey, you can spell it Choffee or you can spell it Choffy (the correct spelling) just don't spell it coffee! Coffee it is not.
Choffy is a brewed chocolate beverage. It doesn't have all of the sugar or preservatives that "hot chocolate" has. It is pure roasted chocolate beans that when brewed like coffee gives a nice rich chocolate flavor. So whether you spell it Choffey, Choffee, or Choffy it is going to be the BEST darn chocolate drink you've ever had.
