Use a grater, vegetable peeler to scrape cheese into pieces. Place in a dehydrator tray and dry at 125°F (52°C) for 8 to 12 hours or until totally dry and easy to crumble. Cover cheese with cheesecloth to prevent cheese pieces from blowing away.
To make cheese powder: Freeze the dehydrated cheese morsels for 10 minutes to make it brittle. Pour in a blender or spice grinder and then process until smooth.
