First cut it in half. Use a big knife, stab through the middle and wedge it down toward the outside. Then take out the knife and repeat on the other side working outwards. (It’s easier that way than trying to cut through the whole thing at once).
Then scoop out the seeds and pulp in the little cavity, and bake it in a 350* oven – face up – for about 45 minutes – or until it looks like it’s starting to dry out and you can easily insert a fork into the flesh. (You can roast it whole, but it takes longer.)
Lastly, when it’s cooled down some, take a fork and scrape out the strands. The more you separate them, the more volume you’ll get! You can do this during the afternoon or the day before since it takes a while and then just microwave it when you’re ready to serve and are hungry.
