I have been making this pie for over 15 years and it is always gets rave reviews. It is a little work because I melt the chocolate on the stove with a double boiler, but worth it. The type of chocolate used makes a big difference in flavor. I use ghirardelli semi-sweet dark chocolate chips. So my pie is dark chocolate in flavor and very rich. You do not need a big piece, so it will usually serve about 20 people. Next time I make it, I am thinking about adding a thin layer of black raspberry jam on the bottom.
