A friend brought this to a dinner party, and it was so wonderful I had to have the recipe. If I make it again, I might strain the orange marmalade first, as I feel it doesn't really fit the texture of the rest of the pie. If you use it as is, be prepared for a very creamy pie with a layer of small orange chunks in between the filling and the crust. For the chocolate cookie wafers, you could either use Nabisco Famous cookie wafers, or Oreos taken apart with the filling scraped out. All substitutions listed in the recipe were suggested by the original chef.
