Combine sugar and water in a small saucepan and bring to a boil, stirring until sugar dissolves; continue cooking 3 to 5 minutes longer. Remove from heat and cool completely.
Place 1 cup of the cooled syrup in a blender with all remaining ingredients (you may need to blend in two batches). Blend 1 minute or until smooth; pour into a pitcher and chill until ready to serve.
