My brother has been experimenting with pumpkin seeds for years, trying out all kinds of flavors. I think he's finally reached some kind of pumpkin seed guru status. This is the recipe he likes best.
If you're using the seeds from your Halloween pumpkin, rinse the pumpkin goo off the seeds and pat dry. You want the seeds to be as dry as possible.
Place them on a cookie sheet and bake in the oven at 250 degrees for 15 minutes or so. This is to dry them out so they'll absorb the sauce.
Return seeds to cookie sheet. Bake at 275 degrees for 30 minutes, then turn them over with a spatula. Sprinkle with garlic salt. Then bake for another 30 minutes or until crunchy.
Other flavor options: cheese (use the powdered mix that comes with macaroni & cheese mixes), soy sauce (use sparingly!), mexican spices. There are a million ways you can make these. Anybody got any more ideas?
