>what is the best way to dissolve chocolate

Hmmm
Chocolate can be melted (in the mouth is the best way)
Chocolate can be emulsified (ganache)
Chocolate can be suspended (hot chocolate)

I don't know if chocolate can be dissolved, because chocolate isn't one
chemical, it's hundreds. Also, the fat portion won't be soluble in the
same medium as the non-fat portion. Probably needs a true food
scientist with chemistry training to give a good answer here, but from
my perspective I'm not sure chocolate can enter solution (i.e., be
dissolved).
