This method is great if you're feeling patient and don't mind waiting a few days for your seeds to dry. Simply spread the seeds out in a single layer on a baking sheet or a piece of parchment paper, and let them sit in a cool, dry place - like a pantry or a cupboard. It's like letting a good book simmer in the back of your mind, waiting for the right moment to pick it up again!
As the seeds dry, you might notice that they start to shrink a bit and turn a lighter color - this is totally normal! It's like when you dry a herb and it loses some of its potency, but still retains its flavor and aroma. And, just like with herbs, you can store your dried pumpkin seeds in an airtight container to keep them fresh for later use.
