In a small saucepan, combine granulated sugar and water. Heat over medium heat for 3-4 minutes, stirring occasionally, until sugar is completely dissolved.
Bring to a simmer and let cook an additional 2-3 minutes. Remove the saucepan from the heat and let cool at least 15 minutes.
Pour the cranberries into the simple syrup and stir to completely coat. Let soak for about 30 minutes.
Then remove cranberries with a slotted spoon and let dry on a wire rack with a piece of parchment paper under it to catch any drops of simple syrup. Let dry for an hour or until cranberries are dry to the touch but tacky.
Place 1 cup of granulated sugar in a bowl, plate or small baking sheet. In batches, roll cranberries in the granulated sugar until completely covered. Repeat with remaining cranberries. Let dry for at least an hour, or until completely dry to the touch.
