By Kris Coronado The Washington Post Posted10/15/2019 11:04 AM After carving a ghoulishly great jack-o'-lantern, don't toss aside the seeds from the pumpkin. Transform them into Pumpkin Seed Clusters to share with Halloween doorbell ringers. One small tip: Pumpkins vary in size, and this recipe is made with a cup of seeds in mind. If you have two cups of seeds, for example, simply double the chocolate and marshmallows. Trying to stop eating these tasty treats? That's a harder trick.
