The first step is to wash the pumpkin and remove the pumpkin flesh. Cut off the stem and the blossom end with a sharp knife.
Cut your pumpkin into manageable pieces that suit your needs.
Then, scoop out the seeds and any pulp with a large spoon. Save the pumpkin seeds for roasting later and wrap in aluminium foil.
Boil pumpkin pieces for 2 minutes then place in cold water to stop cooking.
Place the blanched pumpkin onto a sheet and freeze.
Place the frozen pumpkin into freezer bags for future use.
Notes
If freezing pumpkin puree, place cold puree directly in zip lock bags or into a muffin tray or ice cube tray and then into the zip lock bag before freezing.
