Preparation Combine first 3 ingredients in heavy large sauce pan. Stir over medium heat until sugar dissolves. Increase heat and bring to boil. Pour into medium bowl. Refrigerate until cold, about 2 hours. Strain mint syrup through sieve set over bowl, pressing on mint leaves. Discard mint leaves. Mix bourbon, crème de menthe and minced mint leaves into mint syrup. Process sorbet mixture in ice cream maker according to manufacturer's instructions. Transfer sorbet to container; cover and freeze until firm, about 2 hours. (Can be prepared 2 days ahead; keep frozen.) Freeze 4 parfait glasses for 1 hour. Scoop sorbet into frozen glasses. Garnish with mint sprigs; serve immediately. Note:If you do not have an ice cream maker, you can turn this mixture into a granita—an Italian frozen dessert. Mix an additional 1/2 cup water into sorbet mixture. Freeze until semifirm, whisking occasionally, about 3 hours. Cover and freeze until solid, at least 6 hours or overnight. Using fork, scrape surface of granita to form crystals. Scoop crystals into frozen glasses; serve immediately.
