While most people cannot fathom the appeal of making homemade chocolate, beans to bar that is (I was one of those people), my husband has been pining away at the idea. Apparently making chocolate from beans is done by relatively few companies in the united states and the idea of being among the few in the know was very appealing to him. As well as the fact that he loves fine chocolate.
So here is the process: (Mind you this is over the course of a few days)
Step one: Roast cacao beans. (See pic here) Adjusting temperature and stirring as you go. Step two: The cacao beans are cracked and winnowed, that is, their outer shells are cracked and blown away, leaving the crushed and broken pieces of cacao beans, called "nibs."
Step three: The cacao nibs must now be crushed and ground into a thick paste called chocolate liquor (there is no alcohol in it). Chocolate liquor is pure chocolate in liquid form. (See pic below) Repeat this step several times to make this as smooth and shell free as possible.

Step four: Place Chocolate liquor and other ingredients including sugar, cocoa butter, milk, etc. in a chocolate melanger for the next 12 to 36 hours. Checking frequently and scraping down sides hourly.
