To begin, in a saucepan melt together the syrups, butter, salt, vanilla and rum. Once the mixture is smooth and well combined, remove it from the heat and add the chocolate. If needed, use an immersion blender to homogenize the sauce.
In a separate bowl, beat together eggs and sugar, and incorporate it into the chocolate sauce. Mix well and set aside. At this juncture, nuts can be added to the finished filling or spread in the frozen tart shell.
Montage
Fill the raw frozen tart shell with the nuts, and pour in the filling.
Baking
Preheat fan oven to 330ºF/160ºC. Bake the chocolate pecan pie for 45 minutes. Let cool to room temperature and refrigerate a couple of hours.
Storage
Chocolate pecan pie is best eaten the day after and at room temp. It can be stored a few days in the refrigerator or frozen for up to 3 months. Enjoy!
