First cut off the stems of your pumpkin and cut it in half. Using a spoon remove the seeds and any stringy fibers inside the pumpkin.
Put all of the pumpkin seeds into a bowl, you will want to use these later to make some amazing pumpkin seeds to snack on.
If you have a larger pumpkin then will fit on your baking sheet cut the pumpkin into wedges.
Place the pumpkin on to a baking sheet.
Place the baking sheet with pumpkin in to the oven and bake for 45-50 minutes. Keep an eye on the pumpkin for the last 10 minutes or so, so you do not over cook the pumpkin. The pumpkin is done cooking when the skin begins to shrivel and the pumpkin flesh is tender and can be poked easily with a fork.
Remove the pumpkin from the oven and let it cool until it is cool enough that you can touch it.
Remove the pumpkin flesh from the pumpkin skin. Discard any parts of the pumpkin flesh that are tough.
Add the pumpkin flesh to a food processor or a high-powered blender. Using the puree option puree the pumpkin flesh until it is smooth.
Once done pureeing if the pumpkin puree is a bit dry, add a few tablespoons of water and mix well until it is smooth. Be careful not to add to much water to it, you will want to add the water little by little.
