Preheat oven to 220°C (425°F). Whisk the pumpkin puree, sweetened condensed milk, eggs, spices, salt and brown sugar in a medium bowl until smooth. Then transfer to the pie crust. Bake for 15 minutes.
Reduce the oven temperature to 175°C (350°F) and continue baking for another 40 to 42 minutes or long enough for a knife inserted in the center of the pie to come out clean. Let it cool. Garnish as desired.
