Combine the flour, sugar, and salt in a bowl. Add the chilled butter cubes and mix using your fingertips or a pastry cutter until the mixture turns crumbly. Gradually pour in the cold water, a little at a time, and mix until the dough comes together. Shape it into a ball, wrap in plastic, and refrigerate for 30 minutes.
2 1/2 cups all-purpose flour, 1 teaspoon salt, 1 cup unsalted butter, 2 tablespoons granulated sugar, 1/4 to 1/2 cup cold water
Roll the chilled dough out on a lightly floured surface until it is large enough to line a 9-inch round baking pan. Fit the dough into the pan, pressing gently along the bottom and sides. Trim any excess edges and refrigerate while you prepare the filling.
2 1/2 cups all-purpose flour
Heat the evaporated milk in the microwave for about 2 minutes, or until it is warm but not boiling. This is your scalded milk. Set it aside.
1 3/4 cups evaporated milk
Whisk the eggs and egg yolk together in a separate bowl. Gradually add the sugar while whisking until well combined. Stir in the vanilla extract, then slowly pour in the scalded evaporated milk while continuing to whisk.
3 pieces raw eggs, 1 piece egg yolk, 1 teaspoon vanilla extract, 1 cup granulated sugar
Beat the reserved egg white until soft peaks form, then gently fold it into the milk and egg mixture. This helps give the filling a lighter, smoother texture.
1 piece egg yolk
Preheat the oven to 350°F. Pour the filling into the chilled pie crust. Bake for 15 minutes at 350°F, then reduce the heat to 325°F and continue baking for 30 to 40 minutes, or until the custard is set around the edges but still slightly jiggly in the center.
Remove the egg pie from the oven and let it cool completely at room temperature before slicing. Transfer to a serving plate. Share and enjoy!
