Step 1: Prepare the pie crust: In a food processor, combine the all-purpose flour and salt. Add the cold, cubed butter and pulse until the mixture resembles coarse crumbs. Slowly add ice water, one tablespoon at a time, and pulse until the dough comes together. Form the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes.

Step 2: Roll out the crust: Preheat your oven to 375°F (190°C). On a floured surface, roll out the pie crust to fit a 9-inch pie dish. Trim any excess dough and crimp the edges for a decorative finish.

Step 3: Prepare the custard filling: In a mixing bowl, whisk together the eggs, granulated sugar, vanilla extract, and salt until well combined. Gradually add the whole milk and whisk until the mixture is smooth.

Step 4: Assemble and bake: Pour the custard filling into the prepared pie crust. Sprinkle ground nutmeg evenly over the top for a classic touch.

Step 5: Bake and cool

Place the pie in the preheated oven and bake for 45-55 minutes or until the custard is set, and the top is lightly golden. Remove from the oven and allow the pie to cool completely on a wire rack.

Step 6: Serve and enjoy: Slice and serve your Old-Fashioned Custard Pie at room temperature. Optionally, top with a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence.
