Clean and rinse pumpkin seeds. Pat dry with paper towel to absorb some of the water. In a 250 degree oven, melt one tablespoon of butter on a large cookie sheet. Remove and add one tablespoon of Worchestershire sauce. Scatter seeds onto cookie sheet and stir to coat. Sprinkle with salt to taste. Bake for 1 1/2 - 2 hours, tossing every 30 minutes. Seeds should be lightly browned and crunchy.
The Worchestershire sauce adds a nice tang and the salt can, of course, be adjusted. This recipe will cover approximately 2-3 cups of seeds. I know a single tablespoon of butter and Worchestershire doesn't seem like much, but all you need is a light flavor.
Happy carving from my family to yours!
* As an interesting side note, pumpkin seeds are a natural dewormer for sheep so should you not want to bother with all the sorting, washing and toasting, just slop the whole mess out in the pasture, and your ewes will do the rest!
