How can I preserve the freshness of cranberries by freezing them?

To preserve the freshness of cranberries by freezing them, first rinse and dry the cranberries. Then spread them out on a baking sheet and freeze them until they are firm. Transfer the frozen cranberries to a freezer-safe bag or container, removing as much air as possible before sealing. Label the container with the date and store in the freezer for up to one year.
