You cut the pumpkin in half, and then remove the pulp. Oil the surfaces, and place cut side down in a roasting pan with a bit of water. Bake until the pumpkin is tender. Allow to cool enough to touch. Scoop out the pumpkin and puree it. Pumpkin has a high water content, so you will want to let it drain for a while. Now you have pumpkin puree to use in any recipe!
