Buttermilk Pie With Rhubarb Compote

Preheat the oven to 350 degrees. Have ready a 9-inch pie pan and pie weights for blind baking the crust.

On a lightly floured work surface, roll out the dough to a18/-inch-thick circle and transfer to the pie pan, trimming edges to fit. Allow to rest in the refrigerator for at least 30 minutes (or freeze for later use). Line the chilled pie shell with aluminum foil or parchment paper and weigh it down with pie weights or uncooked beans. Bake for 20 minutes or until light golden brown.

While the crust is baking, make the filling: In the large bowl of a stand mixer or hand mixer, combine the butter and sugar on medium speed for about 5 minutes, until light and fluffy. Add egg yolks one at a time, incorporating after each addition. Reduce the speed and add the flour in increments, mixing well. Slowly add the buttermilk, lemon juice, zest, mace and salt, mixing well. The mixture will form curds; set aside.

In the bowl of a stand mixer or hand mixer, combine the egg whites and salt on medium speed. Beat for a few minutes until frothy, then slowly add the sugar, increasing the speed to high and beating until stiff peaks form. Gently fold the egg-white mixture into the buttermilk mixture and pour it into the pie crust. Bake for 45 to 50 minutes, or until the surface is brown and the center barely jiggles.

While the pie is baking, make the rhubarb compote: Have ready a large rimmed baking sheet.

Zest 1 1/2 oranges; set aside. Juice all three oranges and the lemon; strain into a large saucepan, and add the sugar. Scrape the seeds from the split vanilla bean into the pan and add the ginger. Cook over medium-high heat for about 5 minutes, or until the mixture has reduced to a thick syrup. Add the rhubarb, stirring constantly, over medium-high heat for 5 to 7 minutes, until it is tender but not totally soft. Add the orange zest, stirring to combine. Pour the compote onto the baking sheet and refrigerate until cool, for 20 to 30 minutes.

Serve the pie with a few generous spoonfuls of the compote.
