I've never thought of roasting winter squash seeds before until I came across this recipe a few days ago. We're having roasted butternut squash tonight, so I thought I would give this recipe a whirl. One review said not to wash the seeds, so I didn't, one because if washing is not really necessary why waste the time and water to do it. I did make sure there were no strings hanging from them though. I started them at 275 as given in the recipe, but after 10 minutes, they didn't seem to be doing anything at that temperature, so I cranked the up to 375. That did the trick. They turned out crunchy and tasty. So, if you aren't saving your seeds, or have saved enough, roast them and enjoy.
