This Mexican chocolate is a 70% bar.  It is given its flavor by the vanilla and the cinnamon in the bar.  It is a very good bar to enjoy although it tastes sweeter than it is.  To my knowledge it can only be purchased on line or in Mexico.  On the back of the box the company alludes to the Aztecs mixing chocolate with sugar.  The Mesoamericans actually used honey, or syrups of flowers or fruit.  Sugar did not arrive until Columbus planted it in the Caribbean.  He also encountered cacao beans, but thought them of no value or purpose.  After the Conquest, the Spanish planted more sugar and in a few years developed a taste for the chocolate drink.  Then they were captivated by it.
