2Wash grapes, but do not dry. Roll individually in the sugar mixture and place on a 12 x 17-inch sheet pan so they do not touch. Put the pan in the freezer for about an hour or until grapes are frozen. Remove and eat as a snack or use as a garnish for dessert.
You can substitute powdered ginger, mace, or nutmeg for cinnamon, or divide the grapes into groups and season each group with a different spice. Buon Appetito!
