Preheat the oven to 220 degrees C/gas mark 7.

In a bowl, whisk together the pumpkin puree, condensed milk, eggs, cinnamon, ginger, nutmeg, and salt until smooth.

Pour into the ready made crust.

Bake in the preheated oven for 15 minutes.

Then reduce oven temperature to 175 degrees C/gas mark 3 and continue baking until a knife inserted into the pie comes out clean.

Remove the pie and set aside to cool.
