FRESH PEACH OR NECTARINE SORBET
about 4 cups
Prepare peaches or nectarines and set aside.
In a medium heavy saucepan, combine water and sugar; bring mixture to a boil over high heat, stirring until mixture is dissolved. Remove from heat, cool slightly, and transfer syrup to a blender container. Add 4 cups cut-up peaches or nectarines and lemon juice; cover and blend at high speed until mixture is a puree. Strain mixture, pressing any remaining pieces of fruit with the back of a wooden spoon. Cover and chill puree in the refrigerator until cold. (May quick-chill by placing mixture in a container set in a large bowl filled with ice cubes or crushed ice and cold water.)
Freeze the mixture in an ice cream freezer according to manufacturer's directions. May stir in additional peach or nectarine pieces halfway through freezing process, before sorbet is completely set, if desired. After freezing sorbet, transfer to an airtight freezer container, cover tightly, and continue freezing until firm. Garnish each serving with a sprig of fresh mint and a few slices of additional fresh peaches or nectarines.
