To make simple syrup, combine water and ½ cup of sugar in a saucepan. Bring to a boil, stirring until sugar is dissolved.
Pour the simple syrup into a bowl, then add the cranberries. Cover and refrigerate for 1-8 hours.
Place the ¼ cup sugar in a bowl.
Drain the cranberries well (you can save the syrup if you like). When damp but not dripping, coat the berries with sugar, a few at a time.
Remove and place on waxed paper or parchment to dry, about an hour.
