Cut pumpkin into small manageable pieces and cut off pith and seeds.
Place cut pumpkin skin side up in a large roasting pan. Add 1/4 inch of water and bake uncovered for 1 hour or until tender. Remove from oven and allow pumpkin to cool.
When cooled, cut away skin and mash or puree. Use in any recipe that calls for canned pureed pumpkin.
