Steam pumpkin chunks for about 10 minutes, or until soft.

Once softened, set it aside to cool off for about 20 minutes.

In a medium mixing bowl, combine the steamed pumpkin, brown sugar, eggs, and the mascarpone cheese.

Add cinnamon and nutmeg.

Using a blender, combine all the ingredients together until you obtain a smooth texture.

Add a spoon of semolina (cream of wheat cereal) or rice flour if you want a firmer filling.

Pour the filling into your pre-baked pie crust.
