Pour cider into a 9-inch glass deep-dish pie plate or any other freezer friendly, shallow container.
Place dish into freezer for 2 hours. Remove plate from the freezer and scrape the frozen cider with a fork (see images above). The idea is to shave the ice away with your fork, creating a snowy texture. Place the plate back into the freezer and continue to freeze for another hour. Repeat the scraping process until all of the frozen cider is scraped away, about 4 hours total. Scoop out the frozen cider and place into serving cups. Serve au naturale or topped with some cinnamon spiked fresh whipped cream.
