1. Seed the pumpkin: Preheat the oven to 300 degrees F. Using a spoon, scrape the pulp and seeds out of your pumpkin into a bowl.
2. Clean the seeds: Separate the seeds from the stringy pulp, rinse the seeds in a colander under cold water, then shake dry. Don't blot with paper towels; the seeds will stick.
3. Dry them: Spread the seeds in a single layer on an oiled baking sheet and roast 30 minutes to dry them out.
4. Add spices: Toss the seeds with olive oil, salt and your choice of spices (see below). Return to the oven and bake until crisp and golden, about 20 more minutes.
