This is the chocolate cheesecake I shared as my talent at the recent reunion.
Cheesecake Recipe at Epicurious
I changed a couple of things in the recipe. First I bake the cheesecake in a 12 inch cake pan lined with a parchment paper circle. Cheesecake and spring-form pans have never worked well together for me.
Second I add the chocolate to the batter before the eggs. Otherwise you over-beat the eggs.
Third I serve this with raspberry jam which I sometimes spread under the ganache and sometimes just drizzle over each piece.
