In a food processor, add the pumpkin puree, condensed milk, eggs, cinnamon, ginger, clove, nutmeg, and salt until smooth. Pour into the unbaked pie crust.
Bake in the preheated oven for 15 minutes.
Dial the temperature down to 350°F and continue to bake for 35-40 minutes. Watch the edge of the crust. When it is golden brown or until a knife inserted into the centre of the pie comes out clean.
Allow the pie to cool completely before serving. About 2 hours.
Notes
Top with a generous dollop of whipped cream. I like pumpkin pie to be well chilled, so I make pies a day ahead of time and keep them in the refrigerator overnight with a film on top. However, it's perfectly acceptable to serve room temperature pie too - just be sure to pop the leftovers in the fridge.
