We have celebrated this pie with Thanksgivings and Christmases for over 40 years! The pie is extremely light and of such a high volume, it looks like clouds. We do not normally put whipped cream on top, as this is truly gilding the lily. But then again, it certainly makes it lush. This pie is just a little different than the others posted here, it is spicier and a little bit sweeter. I count chilling time in the passive time, as well as the cooking time. I start this pie in the morning, so I don't feel rushed. It really does take time for the pie to firm up.
I have posted a separate recipe of the Recipe #408669 for anyone who needs more detailed instruction and more pictures.
