We roast them with a sprinkle of cinnamon and cloves.
@MichaelS, the pumpkins at the store are probably hybrids and yeah, they're unlikely to grow from seed, at least not true to the parent plant. Grab a packet of heirloom pumpkin seeds and give it a whirl.
You mean none of you guys have seed fights? Pumpkin seeds are slippery. You're supposed to get a few in your hand, and press an individual seed between your fingertips so it pops out at your siblings, spouses, children, really just whoever is near. Go for it @Charli1. You've already got the upper the hand since your kids don't know about it.
I have never given much thought to how useful pumpkin seeds can be. Thanks to this thread, now I have an idea of how to experiment. I have always known that they are full of valuable nutrients and high in fiber.
