Add the flour and salt to a large mixing bowl. Cut the butter into small cubes and add to the bowl. Use clean dry hands to rub the butter into the flour until it resembles sand and the butter is no larger than the size of a pea.
Spoon in the ice water and use a butter knife to combine the ingredients together. Pour the pie dough out onto the work top and form into a ball. Cover and place in the fridge for at least 30 minutes.
Roll the chilled pie dough out to 1/8" or 1/2 cm thick and place in a 8" or 20cm pie dish. Cut off the excess pastry and using your thumbs and finger pinch the edges of the dough. Place into the fridge until ready to use.

Notes
If you are using homemade pumpkin puree, cut a pumpkin in half and bake face down for around 40 minutes at 200C or 400F until soft. Leave to cool before scooping out the flesh and blending. Squeeze out as much moisture as you can by wrapping the pureed pumpkin in a tea towel and squeezing.White sugar can be replaced with brown sugar for a more caramel flavour to the pumpkin pie.Evaporated milk can be replaced with cream or half and half.
