Storing raw cranberry
According to the Cranberry Institute:


  Yes. In fact cranberries freeze very well either whole or sliced.
  Sealed in an airtight container frozen cranberries will keep for
  nearly a year.


Personal experience bears this out as well, with unsweetened cranberry dressing (fresh cranberries and orange zest, zapped in a food processor. Thaw, add sugar to one batch for those who like it traditional, and splenda to the other for dieters and diabetics.)
