Chocolate sauce

I want to make a note of this because 3 out of 4 of us really like it.  The other person?  I stirred some of the chocolate sauce into a glass of milk and a certain small someone complained "This tastes like nothing! It's worse than nothing!"  Too bad for you, little guy.  The rest of us like it.  I think his problem is that it tastes like dark chocolate which is not necessarily a bad thing.  It's this one from Allrecipies.
