you also need to know more about the chemistry involved with
chocolate...you can only melt it at certain temperatures and you would
need to temper it. to freeze it would cause it to turn grey...not
appetizng for sales...the best bet for chocolate cotton candy, which
is an awesome idea, might be to incorporate the cocoa in the mix...i
hope you play with this, after you have learned more about the
chemistry, which is not hard, of chocolate. the chocolate if heated
and then flash frozen would shatter...it has to be part of something
that "carries" it...something that it is added to...and the other
poster who advised that cocoa added to the mix was/is on the right
track.
