How to cook pumpkin:
Bring 1 inch of salted water to a boil in a large kettle. Add unpeeled pumpkin chunks. Return to a boil; reduce heat and simmer, covered 25-30 minutes or until fork tender. Drain. Peel when cool enough to do so. Or peel 1 1/2 to 2 inch chunks and cook about 10 minutes after water returns to a boil.
Cut a small pumpkin in half and clean out cavity. Place flesh side down in a cake pan or cookie sheet with sides. Add a little water. Bake at 350º for 1 1/2 hours or until pumpkin is fork tender. Scrape out and mash or puree in the blender. Use in recipes that call for mashed pumpkin or freeze for later use.
Pumpkin can also be cut into 3-inch unpeeled pieces and baked, covered at 375º approximately 40 minutes. Cool, peel, and mash or puree in a blender.

Wash pumpkin. Cut or break into uniform pieces (or cut in half) and remove seeds. Place cut side down on baking sheet and bake at 350º to 400º until tender. Cool. Scoop out pulp; mash or put through ricer; thoroughly chill before packaging, leaving 1 inch headspace in rigid containers.
