Bring your pumpkins home and cut them in half. Have the kids scoop out the seeds and stuff. They seem to enjoy this while I think it is just slimy. Save the seeds to roast. Roasted pumpkin seeds are such a yummy snack.
Next you want to roast your pumpkin. I place mine cut side down in a pan of water. (Hint: pour the water in after you have placed you pan on the rack in the oven, otherwise water may splash everywhere.) Roast in the oven for about an hour or so. The oven temp can be anywhere from 350-400. You can pierce the pumpkin with a fork to judge the doneness. It needs to be soft.
