Line a baking pan with a silicone mat, aluminum foil or plastic wrap and set a wire cooling rack on top.
In a small bowl, toss one cup of cranberries in ¼ cup of the spiced simple syrup. Remove with slotted spoon and place on wire rack. Let cranberries set on the wire rack for at least an hour.
Place the granulated sugar in a medium bowl or Ziploc bag, and toss the sticky cranberries until well coated. Refrigerate prepared cranberries for at least an hour before using. Cranberries can be refrigerated for up to a week.
