I have a dear NASA engineering buddy who is multi talented. He has won so many ribbons at different cooking contest. Quiet amazing cooking abilities. I dropped by his home to deliver several bags of pecans and he was cooking up scrumptious dishes. Everything has to be down to a science. This is one recipe he gave me. I haven't tried it but if he says it's good head for a fork and dish.
Heat eggnog until it nearly simmers. Remove from heat and add chocolate chips. Stir until chips are dissolved and mixture is smooth. Let cool. Add milk and gelatin stirring until mixture begins to thicken. Whip the heavy whipping cream until peaks form then fold in the eggnog mixture and stir until well mixed. Pour into a graham cracker pie crust and refrigerate 2 to 3 hours before serving.
