Put the 1 cup of sugar and ½ cup of water in a small saucepan and bring to a gentle boil, stir well to dissolve the sugar. Cook on a low boil for about 10 minutes. Remove from the heat and let it cool down.
Once the simple syrup has cooled down, add the cranberries to the syrup and mix well until they are coated with the syrup.
Put the ½ cup of sugar on a plate. Use a slotted spoon to remove the cranberries from the syrup and roll them in the sugar.
Use a regular spoon to transfer the sugared cranberries to another plate, lined with a paper towel or wax paper, to let them dry for about 30-45 minutes.
