What kind of chocolate should I use to coat homemade turtles? I am making chocolate treats with mini Presley's caramel and chocolate. Can I use a regular Hershey's bar or use baking chocolate or can I mix them to make a harder coating or will the regular harden?
There are certain kinds of chocolate that are formulated for coating. Couverture is one of the names.  My local grocery store has discs of chocolate that come in packages that are meant for this.  Here's a link to a good explanation of the differences.
