Before roasting your seeds, you’ll want to clean and soak them for at least an hour. Cover the seeds with water in a small mixing bowl, and add about ½ teaspoon of sea salt to the water. Stir everything around, and let the seeds soak at least an hour, or up to 8 hours.
Drain the seeds in a strainer, rinse, and remove any pumpkin flesh left behind. Put the seeds on a paper towel to soak any excess water, and gently pat dry. They won’t get totally dry unless you let them sit out overnight (which you can do if you want!). I usually don’t and they crisp up just fine.
Pour the seeds onto a baking sheet, and toss them with melted butter and sea salt. If you are flavoring your seeds at all, you will add those seasonings here as well.
Spread the seeds out on the baking sheet, and bake at 350 degrees for 15 minutes. Stir the seeds around and bake for another 7-10 minutes until golden and fragrant. The seeds will crisp as they cool.
Store your seeds in an airtight container in the pantry for 2 weeks.
