This cheesecake is impressive to look at and to eat. The steps are easy but it takes some time to prepare. However, it freezes beautifully for up to a month, so it can be prepared far in advance of your event. I have made this cheesecake many times as a birthday cake. Use a high quality chocolate in this recipe, not chocolate chips or baking chocolate. Try Valrhona, Callabeut or Lindt, which you can get at many grocery stores. Lindt bars come in 3 oz. bars. Also, this cake must bake at the temperature directed or it will be raw in the middle and overdone on the edges.
