We carved two pumpkins and got a cup of seeds from each. Here's my recipe:
Cover the seeds in a pot of water with I TBSP of salt per cup of seeds. Bring to a boil and simmer for 10 minutes. Drain and spread the seeds out on a tea towel to dry overnight.
Later put the seeds in a greased baking dish. Mix seasoning (this is for 1 cup of seeds - double if you have more): 1 TBSP melted butter, 1 TSP Worcestershire's sauce, and 1/4 tsp garlic salt. Pour over seeds, then bake at 250 degrees for 1 hour stirring every 10 minutes.
I was completely prepared for the kids to think these looked yucky, and refused to try them. Instead, I was surprised by how quickly they gobbled them up - and they even shared, too. I've got the picture to prove it!
