Yes to everything Charles said.
If you would like to make a ganache that is sweeter or has the flavor of milk chocolate, use the chocolate specified in the recipe, then you can add sugar to the hot cream. I find that Callebaut bulk dark chocolate (my grocery sells it in the cheese section) gives a milder, more milk-chocolate flavor ganache. The other thing you can do is substitute a tablespoon or two of whole milk for the same amount of cream in the ganache. It will mellow (some might say dull) the chocolate flavor and give you something closer to the taste of milk chocolate. I wouldn’t use very much, though, or you will loose the beautiful chocolate-cream flavor of the ganache.
All that said, if you want to try the dark chocolate chipits, you can make a little bit of ganache by melting a small amount with a little cream in the microwave (short bursts), cool, and see how it tastes and what the texture is like.
