Break off the stem. Cut in half. Scoop out the seeds. Bake on a cookie sheet for 1-1/2 hours until soft, or in a microwave for about 15 minutes per half, or until soft like a baked potato. Measure as the recipe requires. Any recipe will be better if the pumpkin is mixed with the milk and eggs in the pitcher of a blender (not a mixer).
Butternut squash can be substituted for pumpkin in most pumpkin recipes.
