I'm sure there are as many recipes for pumpkin seeds as there are for, oh say, chicken soup or lasagna. This is how I make pumpkin seeds, this is how I've always made pumpkin seeds for as long as we have been guttin' pumpkins.
Rinse the seeds and remove as much of the pulp as you can. Spread the seeds out on a cookie sheet and let them dry for at least 8 hours, preferably overnight. Turn them every few hours so they dry evenly.
