Steam the pumpkin for ten minutes or so until soft.
Preheat the oven to 220 degrees C (200 for fan ovens) orĀ 430 degrees F.
When the 30 mins are up, remove the dough from the fridge. Divide into two pieces and roll out on a clean, floured surface to about 1/4 inch, and cover the base and sides of two flan or pie dishes.
Place a sheet of greaseproof paper on the top of each pastry base and cover in baking beans.
Blind bake the pastry bases in the oven for 5-10 mins.
Meanwhile, add the ingredients for the filling to a large blender or food processor. Blend until smooth, adjusting the amount of sugar and spices if necessary, according to taste.
When the pastry is ready, remove from the oven and remove the baking beans and greaseproof paper. Turn the oven down to 180 degrees C (170 for fan ovens) or 360 degrees F.
Fill the pies with the pumpkin mixture and bake in the oven for 50-60 minutes, or until golden brown and mostly firm (the mixture will still look a little wobbly).
Remove from the oven and allow to cool before storing in the fridge for at least 2 hours, ideally overnight.
Serve with vegan cream.
