Preheat the oven to 375ºF. Line the pie shell with (crumpled) parchment paper and fill it with pie weights, granulated sugar, or dried beans.
1 9 inch Pie crust
Bake until the crust edges start to brown, about 15 minutes. Remove the pie shell from the oven and lift the parchment paper (with the weights) out of the pie. With a fork, prick holes all over the bottom crust. Return the pie crust to the oven. Bake another 7-8 minutes. Let cool before pouring the pie filling into the crust.
Increase the temperature of the oven to 425ºF.
In a bowl whisk together the pie filling ingredients until smooth. Pour into the cooled pie shell.
1 3/4 cup Apple butter, 1 cup Heavy cream, 3 large Eggs, 1/2 cup Dark brown sugar, 1 tsp Ground cinnamon, 1/4 tsp Ground nutmeg, 1/8 tsp Ground cloves, 1/4 tsp Kosher salt
Bake the pie for 15 minutes at 425º, then reduce the oven temp to 350ºF and bake another 35-30 minutes. The center should still be slightly jiggly.
