Step One: Cut the top off the pumpkin, with knife at an angle, so the top can be placed back onto the pumpkin without falling through the hole (assuming you will be using this pumpkin as a jack-o-lantern later.
Step Two: Remove the seeds from the pumpkin, and separate the seeds from the orange, gooey, stringy stuff.
Step Three: Place seeds in bowl with water, and rub the seeds through your hands to help remove the last remaining bits of stringy bits.
Step Four: Pour seeds into colander to strain the water out. Remove any last remaining pieces of stringy bits.
Step Five: Pour seeds onto paper towel, and pat them dry.
Step Six: Preheat oven at 300 degrees.
Step Seven: Place seeds into bowl, and drizzle olive oil onto seeds. Add a little Worcester sauce and then sprinkle salt onto seeds. Mix well.
Step Eight: Spread seeds out evenly in single layer onto baking pan.
Step Nine: Bake for 20-30 minutes in preheated oven. Every few minutes, stir the seeds around to prevent sticking to the pan.
Step Ten: Remove from oven, cool, and store in tupperware bowl.
That's it! Eat and enjoy your roasted pumpkin seeds.
