Wash cranberries and discard any damaged ones. Place in a bowl. Combine sugar and water in a pot and heat until simmering. Stir until sugar is dissolved and let cool for a few minutes until warm (not hot). Pour over cranberries and let sit in fridge, covered, overnight. Use a slotted spoon to remove berries from syrup. Set berries on a cooling rack that is placed over foil to collect drips. Spread berries out so they are not touching each other. Let dry for 1 hour. Roll berries a handful at a time in sugar (use the two-sugar technique from the notes if desired.) Place sugared berries on a baking sheet, or foil, etc. and let dry for an hour or two.
