Prepare the crust: If using homemade crust, roll it out and fit it into a 9-inch pie pan. Trim and crimp the edges. Chill while preparing the filling.
Preheat oven to 425°F (220°C). Place a baking sheet in the oven to heat.
In a large bowl, whisk together pumpkin puree, granulated sugar, brown sugar, cinnamon, ginger, nutmeg, cloves, and salt until well combined.
Beat in the eggs and egg yolk until smooth. Gradually whisk in evaporated milk (and vanilla, if using). The filling should be creamy but not overly runny.
Pour filling into prepared crust. Place the pie dish onto the preheated baking sheet.
Bake at 425°F for 15 minutes, then reduce temperature to 350°F (175°C) and continue baking for 40–50 minutes, or until the center is just set and a knife inserted near the edge comes out clean. The middle should still jiggle slightly.
Cool completely on a wire rack, then chill for at least 2 hours before slicing.
Serve topped with whipped cream or your favorite garnish.
