I lived in the deep south for over 20 years and have tasted hundreds of sweet potato pies. This is the best recipe I've tried. It's the only one I make now. I find the flavor more complex if you bake the sweet potatoes instead of boiling them. Baking them in a slow oven until they begin to caramelize really brings out their flavor.
- Put sweet potatoes and butter in mixing bowl and mix until butter is well incorporated.
- Add the rest of the ingredients and mix on medium speed until smooth.
- Pour into unbaked pie crust and bake on middle rack in a 350°F oven for 40 - 50 minutes or until done.
- Serve with whipped cream or Cool Whip.
