Preheat the oven to 180C/360F.
Cut the Pumpkin into quarters.
These will be large pieces.
Place the pumpkin onto a baking tray, skin side up.
Bake in the oven for 45-60 minutes (the length of time will depend on the thickness of your pumpkin pieces).
Remove from oven and allow to cool completely.
Remove the skin from the pumpkin and mash/purée the baked pumpkin.
The pumpkin will be moist.
Whilst the pumpkin is in the fridge some water may be released. Discard the water before using (otherwise your baked item will end up mushy).
