This recipe came to The Times in 1983 from the renowned Louisiana chef Paul Prudhomme. Like its traditional pecan cousin, this pie is very sweet, so serve it with a little Chantilly cream on top.
01Make the crust: Cream butter and sugar until light and fluffy. Add beaten egg and milk; beat about 2 minutes. Stir in flour to moisten ingredients. Turn out onto a lightly floured work surface and shape into a disk. Wrap with plastic wrap and refrigerate at least one hour.
02Roll out dough into 14-inch circle on lightly floured wax paper, or on a lightly floured work surface. Transfer to a deep 9-inch pie plate; remove wax paper if using. Press pastry into plate and flute edges.
03Heat oven to 300 degrees.
04Make the sweet potato filling: In a large bowl, combine potato, butter, vanilla, brown sugar, cinnamon, nutmeg, allspice, salt, beaten egg, heavy cream and sugar. Beat at medium speed until mixture is smooth. Spread on bottom of pie crust.
05Make the pecan filling: Sprinkle sweet potato filling with pecans. In another bowl, combine sugar, eggs, melted butter, corn syrup, salt, cinnamon and vanilla and beat well. Pour over pecans.
06Transfer pie to oven and bake for 1 1/2 hours. Cool.
07Make the chantilly cream: Whip heavy cream with sugar, orange liqueur and Cognac. Top each slice of pie with a dollop of cream.
