I have just carved my Halloween pumpkin and I want to roast the seeds in my oven. I have already cleaned all the seeds off and rinsed them well. What should be the temperature of the oven? Can I season them before keeping in the oven? How long do I need to roast them? Is it necessary to keep them at a very close source of heat i.e. at the top rack? Can someone advice on how to roast pumpkin seeds in the oven for its recipe?
