I always just bake the pumpkin in the oven . i cut the pumpkin in half , scoop out all the seeds (put them in a bowl of water to soak , this helps with cleaning of the pumpkin seeds) and lay it open side down on a cookie sheet and bake at 350 for about 30 min. depending on the size. Just poke it with a fork to see if its tender or not!
After its done take it and peel off the skin, most of it will peel easily, then just cut it up, either can it, freeze it or use it for some of the recipes i have on here!
Heres what i do with the pumpkin seeds(also i do this with the sunflower seeds we grow)
take them out of the water i had them soaking in, clean the up a bit, its ok if theres still pumpkin goop on them, now i put them in a bowl of salt water for a few hour to overnight to soak. When i can get to them i strain them and spread a bit on a cookie sheet, put in oven and roast at 350 for about 15 or so min. They roast up pretty fast so keep an eye on them. Take them out, cool off, and put in plastic bags or jars to store!
