Ingredients:
- 1 ½ cups (190g) All-purpose flour
- ½ tsp (3g) Fine sea salt
- ½ cup (113g) Cold unsalted butter, cubed
- ¼ cup (60ml) Ice-cold water
- 2 cups (450g) Cooked, mashed sweet potatoes
- ½ cup (115g) Unsalted butter, melted and cooled
- 1 cup (200g) Granulated white sugar
- ½ cup (120ml) Evaporated milk
- 2 Large eggs, room temperature
- 1 tsp (5ml) Madagascar vanilla extract
- ½ tsp (1g) Ground nutmeg
- ½ tsp (1g) Ground cinnamon
- ¼ tsp (1.5g) Salt
Instructions:
- Roast the sweet potatoes whole in their skins at 350°F (175°C) for about 60 minutes, or until very tender. While hot, peel away skins and pass the flesh through a ricer or fine-mesh sieve into a large bowl.
- Mix flour and salt in a bowl. Cut in cold, cubed butter until coarse crumbs form with pea-sized chunks. Drizzle in ice water and toss until dough just holds together. Wrap and chill for at least 30 minutes.
- Roll out the chilled dough on a lightly floured surface to a 12-inch diameter. Drape over a 9-inch pie plate, trim edges, and crimp. Par-bake the crust for 15 minutes.
- Whisk the melted butter into the warm mashed potatoes until fully incorporated and no yellow streaks remain.
- Add the granulated sugar, evaporated milk, vanilla, nutmeg, cinnamon, and salt. Whisk vigorously to combine.
- Fold in the room-temperature eggs one at a time to ensure the emulsion bonds correctly.
- Pour the mixture into the par-baked crust. Bake at 350°F (175°C) for approximately 50 minutes or until the edges are set but the center is still slightly jiggly.
