Remove the corn from the husks. In a large, deep bowl, slice off the kernels of corn. With the dull side of the knife (or a regular dinner knife), press and scrape the cob all the way down to remove all the bits of kernel and creamy milk inside. Add heavy cream, salt to taste, a generous amount of ground pepper and butter; mix well. Pour mixture into a baking dish. Bake at 350Fº for 30 to 45 minutes or until thoroughly warmed through.
