I am not sure where I originally found this recipe. I know that we made it a few times in our travels for potlucks so I have had it for all -most?- of the time I have been married. I never tell what the secret ingredient is until people have tried this recipe and say they like it. Most think it is coconut, so why ruin it for them?
The recipe says it makes 2 pies, but we usually bake it in a 9×13 casserole dish and cut it into squares. For a gluten free crust, see notes.
