In a large mixing bowl, whisk together the pumpkin puree, sugar, cinnamon, ginger, cloves, and salt.
Beat in the eggs, then stir in the evaporated milk.
Pour the mixture into the unbaked pie crust.
Bake for 15 minutes. Reduce the temperature to 350°F (175°C) and bake for another 45 minutes, or until a knife inserted near the center comes out clean.
Cool on a wire rack for 2 hours. Serve immediately or refrigerate.
Notes:
For best results, use fresh pumpkin puree instead of canned.
