Preheat your oven to 425°F (220°C).
In a mixing bowl, combine the pumpkin puree, sugar, cinnamon, nutmeg, cloves, and salt. Mix until well blended.
Beat in the egg and then gradually add the evaporated milk. Continue mixing until the filling is smooth.
Roll out your pie crusts and use a round cutter (about 3 inches in diameter) to cut out circles. Press each circle into your mini tartlet pans or muffin tin.
Spoon the pumpkin filling into each pastry shell, filling them about 2/3 full.
Bake in the preheated oven for 15 minutes. Then, reduce the temperature to 350°F (175°C) and bake for an additional 20-25 minutes, or until the filling is set and the crusts are golden brown.
Let the Mini Pumpkin Pie/Tartlets cool in the pans for a few minutes, then transfer them to a wire rack to cool completely.
Once cooled, these little delights are ready to enjoy!
