Well i dont have time in school to drink coffee so i figured why not infuse it in chocolate? So i added some to the chocolate and i was wondering how i should try and harden it.
I tried to thicken it back up on the stove for a little while. But should i put it in chilled conditions or leave it in room temperature conditions?

Well, the problem is, if you're using real chocolate, you're not supposed to add water to it...ruins it. I do believe that espresso has water in it, right?
The only hope, if it hasn't thickened up would be to chill it...but I don't know if it will work.
Good luck!
