With pumpkins in season an article I posted Pumpkin Recipes, often times recipes call for canned pumpkin however it is possible to make your own puree rather then using the canned.
I usually add a little seasoning in the baking process i feel it helps give it a little zing it is not necessary to add this step it really depends on what I am making it for if its for a dessert I do, if its to add to a main dish or side dish...
