Preheat your oven to 400°F.
Cut your pie pumpkin in half, and remove all of the seeds and pumpkin guts.
Chop the pumpkin into pieces and place on a baking sheet.
Cut off the top of the head of garlic so all cloves are exposed, and place on the baking sheet with the pumpkin pieces.
Drizzle with 2 tbsp extra virgin olive oil, sprinkle with salt, and roast for 45 minutes to an hour.
Let the pumpkin cool, then remove the rind from the roasted pumpkin.
Add the roasted pumpkin to a food processor along with the roasted garlic (you can squeeze it right out of the skin).
Pour in 1 cup of heavy cream and 1 cup of water, and blend until smooth.
