So I am a big chocolate fan.  For something that has been around since 1900 BC, it still is pretty awesome today
I love it made in the form of a block to cook with
You are referring to baking chocolate.  That is the very dark chocolate and it is great to melt into deserts.  
The cacao seed have a bitter taste before they are fermented
Yes, chocolate it its purist forms is very bitter and not great to eat by itself.  I actually like dark chocolate items myself
I like all chocolate and after fermintation the beans have to be roasted, smells delish!
