Ingredients:
- 1.25 cups (150g) all-purpose flour
- 0.5 tsp (3g) salt
- 0.5 cup (115g) unsalted butter, chilled and cubed
- 4 tbsp (60ml) ice water
- 2 lbs (900g) sweet potatoes, roasted and peeled
- 0.5 cup (100g) brown sugar, packed
- 0.5 cup (120ml) unsalted butter, melted
- 2 large (100g) eggs, room temperature
- 0.75 cup (180ml) evaporated milk
- 1 tsp (5g) ground cinnamon
- 0.5 tsp (2g) ground nutmeg
- 0.25 tsp (1g) ground ginger
- 0.5 tsp (3g) salt
Instructions:
- Prick the sweet potatoes several times with a fork, place on a baking sheet, and roast at 400°F (200°C) for 45–60 minutes until tender. Allow to cool slightly and peel away the skins.
- Pulse flour and salt in a food processor, then cut in chilled cubed butter until the mixture resembles coarse crumbs.
- Gradually add ice water until the dough just holds together. Roll out on a floured surface to a 12-inch circle, fit into a 9-inch deep-dish pie plate, and trim the edges.
- Chill the prepared crust in the freezer for 10 minutes to prevent shrinkage during baking.
- Mash the roasted potatoes until smooth.
- Using a mixer on low speed, incorporate melted butter, brown sugar, cinnamon, nutmeg, ginger, and salt.
- Beat in eggs one at a time, then slowly stream in the evaporated milk until the batter is glossy and uniform.
- For an ultra-smooth texture, pass the filling mixture through a fine-mesh sieve.
- Pour the filling into the chilled crust, smoothing the top with a spatula.
- Bake at 350°F (175°C) for 45–55 minutes until the edges are set and the center has a slight jiggle.
