For Pumpkin muffins we prefer not to use true pumpkin, it is too stringy. This one is a Georgia Candy Roaster, a squash, we were not sure when we bought the seeds if it would grow here because it requires 120 days and that is a little longer than our season allows. But I am glad we tried because it is a sweet and very good tasting squash. Other squash we use are hubbard, banana, or acorn. We grow tons of pumpkins and squash for our livestock so there is always a lot to choose from.
cut the squash into chunks then use a potato masher until the squash is creamy.
