Making Chocolate from Cacao Nibs

Here is another fail in my kitchen experiments.  I'll leave you with some pictures of my attempt to make chocolate from Cacao Nibs.  

I tried to make it using the "cheat" way and placed a handful of cacao nibs in a food processor and pulsed it....for over 30 minutes until I slowly started to see the nibs start to liquefy.

Here's the final product. Grainy, liquefied cacao nibs.  It had a deep dark chocolate taste, but it was gritty in texture. I think I have to invest in one of those power blenders that Jamba Juice uses and Costco sells to liquefy my cacao nibs.  Meh, it was worth the initial experiment, but I don't know if I really want to attempt to make chocolate this way again.
