So, my boyfriend is looking for a new way to make unsweetened hot chocolate. Ideally he'd like to use ground or fine powder-like chocolate, but specifically chocolate (without the cocoa butter removed) rather than cocoa powder. Also, he'd like something unsweetened, which rules out grating a standard or even fancy bar of chocolate into a cup with some milk/cream/etc.
Any ideas? Know of a source for excellent quality unsweetened chocolate, either in a bar to grate or already grated/ground? Anyone made hot chocolate this way in the past?
I've done an unsweetened one with cocoa powder already: cocoa, milk, vanilla, almond extract, cinnamon, a dash of cayenne, and a dollop of cream.
Thanks for any ideas!
